We do not provide road hazard coverage. In some cases tire retailers may offer and administer their own road hazard warranty programs. Typically, retailers will offer a customer the opportunity to purchase a road hazard warranty only in conjunction with the purchase of new tires. We play no role in retailer road hazard warranty programs and do not maintain any listing of retailers that offer such coverage. You may wish to contact participating dealers in your area and inquire if they would be willing to sell such coverage to you.

Check the cold inflation pressures in all your tires, including the spare, at least once each month
Failure to maintain correct inflation may result in improper vehicle handling and may cause rapid and irregular tire wear, sudden tire destruction, loss of vehicle control and serious personal injury. Therefore, inflation pressures should be checked at least once each month and always prior to long distance trips. This applies to all tires, including sealant types, and Self-Supporting tires which are as susceptible to losing air pressure as any other type of tire if not properly maintained.
It is impossible to determine whether tires are properly inflated by simply looking at them. It is almost impossible to “feel or hear” when a tire is being run underinflated or nearly flat. Tires must be checked monthly with a tire pressure gauge.
Pressures should be checked when tires are cold, in other words, before they have been driven on. Driving, even for a short distance, causes tires to heat up and air pressure to increase.
Checking pressure when tires are hot:
If pressures are checked after tires have been driven for more than three minutes or more than one mile, (1.6 km) the tires become hot and the pressures will increase by approximately 4 psi. Therefore when the tire pressure is adjusted under these conditions, it should be increased to a gauge reading of 4 psi greater than the recommended cold inflation pressure.
Tire pressure monitoring systems (TPMS)
Your vehicle may be equipped with a Tire Pressure Monitoring System (TPMS) that is designed to monitor the pressure of tires mounted on your vehicle and sends a signal to the driver if a tire pressure falls below a predetermined level. A TPMS should not replace monthly manual pressure checks for all four (4) tires and the spare. We recommend that you manually monitor and check tire pressure inflation with a pressure gauge. Your tires should have the recommended pressure listed by your vehicle's manufacturer. This information can be found in the vehicle owner's manual and often on a placard located in the vehicle's door jamb, inside the fuel hatch, or on the glove compartment door. If you have a plus size fitment that requires a higher inflation pressure, your tire pressure monitoring system will require re-calibration to the new inflation pressure. Refer to your tire dealer/installer of plus size tires for proper inflation pressure.
We recommend checking air pressure once each month, and before a long trip. Whether you have a full-sized or mini-spare, make sure that it is properly inflated as well. If the TPMS generates improper monitoring or signals we recommend that you consult your owner’s manual provided with your vehicle and follow-up with your vehicle’s manufacturer.
Inspect your tires, do not drive on a damaged tire or wheel
Objects in the road, such as potholes, glass, metal, rocks, wood, debris and the like, can damage a tire and should be safely avoided. Unavoidable contact with such objects should prompt a thorough tire inspection. Anytime you see any damage to your tires or wheels, replace with the spare at once and immediately visit any BFGoodrich® tire retailer.
A tire impacted by a road hazard (curb, pothole, debris) may be damaged but not have visible signs of damage on its surface. A tire damaged by an impact may sustain a sudden failure a day, week, or even months later. You may not recall hitting an object that damaged or injured your tires. Air loss, unusual tire wear, localized wear or vibrations can also be signs of internal tire damage.
If you suspect any damage to your tire or wheel from an impact with a curb, pothole, debris on the road or any other road hazard, or if you feel or hear any unusual vibration, replace with a properly inflated spare at once and immediately visit any qualified tire technician.
Always look for bulges, cracks, cuts, penetrations and abnormal tire wear, particularly on the edges of the tire tread, which may be caused by misalignment or underinflation. If any such damage is found, the tire must be inspected by any BFGoodrich® tire retailer at once. Use of a damaged tire could result in tire destruction.
BFGoodrich® tires contain “Wear-Bars” in the grooves of the tire tread which show up when only 2/32nds of an inch (1.6 mm) of tread is remaining. At this stage, your tires must be replaced. Tires worn beyond this stage are extremely dangerous.
Do not overload - Driving on any overload tires is dangerous
The maximum load rating of your tires is molded on the tire sidewall. Do not exceed this rating. Follow the loading instructions of the manufacturer of your vehicle and this will ensure that your tires are not overloaded. Tires which are loaded beyond their maximum allowable loads for the particular application will build up excessive heat that may result in sudden tire destruction. Do not exceed the gross axle weight rating for any axle on your vehicle.
Wheel alignment and balancing are important for safety and maximum mileage from your tires
CHECK HOW YOUR TIRES ARE WEARING AT LEAST ONCE EACH MONTH
If your tires are wearing unevenly, such as the inside shoulder of the tire wearing faster than the rest of the tread, or if you detect excessive vibration, your vehicle may be out of alignment or balance. These conditions not only shorten the life of your tires but adversely affect the handling characteristics of your vehicle, which could be dangerous. If you detect irregular wear or vibration, have your alignment and balance checked immediately. Tires which have been run underinflated will show more wear on the shoulders than in the center of the tread.
Tire rotation and replacement
To obtain maximum tire wear, it may be necessary to rotate your tires. Refer to your vehicle owner’s manual for instructions on tire rotation or refer to https://www.bfgoodrichtires.com/auto/learn/maintenance/tire-rotation. If you do not have an owner‘s manual for your vehicle, BFGoodrich® recommends rotating your tires every 6,000 to 8,000 miles (10,000 to 13,000 km) or 3,000 to 5,000 miles (5,000 to 8,000 km) for off-road oriented tires. Monthly inspection for tire wear is recommended. Your tires should be rotated at the first sign of irregular wear, even if it occurs before 6,000 miles (10,000 km) or 3,000 miles (5,000 km) for off-road oriented tires. This is true for all vehicles. When rotating tires with a directional tread pattern, observe the arrows molded on the sidewall which show the direction the tire should turn. Care must be taken to maintain the proper turning direction. Determine whether rotated tires require tire inflation adjustment as front and rear position tire pressure may vary according to the vehicle manufacturer’s specification due to the actual load on that wheel position. Some vehicles may have different sized tires mounted on the front and rear axles, and these different sized tires have rotation restrictions. Always check the vehicle owner’s manual for the proper rotation recommendations.
Full-size spare tires (not temporary spares) of the same size and construction should be used in a five (5) tire rotation. Always check the inflation pressure of the full-size spare immediately before incorporating it into rotation. Follow the vehicle manufacturer’s recommended pattern for rotation, or if not available, see a qualified tire technician.
REPLACEMENT OF TWO (2) TIRES
It is recommended that all four (4) tires are replaced at the same time. However, whenever only two tires are replaced, the new ones should be put on the rear. The new tires, with deeper tread, may provide better grip and water evacuation in wet driving conditions.
Do not make or allow to be made any alterations on your tires. Alterations may prevent proper performance, leading to tire damage which can result in an accident. Tires which become unserviceable due to alterations such as truing, whitewall inlays, addition of balancing or sealant liquids, or the use of tire dressing containing petroleum distillates are excluded from warranty coverage.
Repairs - Whenever possible, see your BFGoodrich® tire retailer at once
If any BFGoodrich® tire sustains a puncture, have the tire demounted and thoroughly inspected by any BFGoodrich® tire retailer for possible damage that may have occurred.
A tread area puncture in any BFGoodrich® passenger or light truck tire can be repaired provided that the puncture hole is not more than 1/4” in diameter, not more than one radial cable per casing ply is damaged, and the tire has not been damaged further by the puncturing object or by running underinflated. Tire punctures consistent with these guidelines can be repaired by following the Rubber Manufacturers Association (RMA) recommended repair procedures.
Repairs of all tires must be of the combined plug and inside patch type. Plug only repairs are improper. A tire should be removed from the rim and inspected prior to repair. Any tire repair done without removing the tire from the rim is improper. An improperly repaired tire will cause further damage to the tire by either leaking air or allowing air, moisture and contaminants to enter the structure of the tire. An improperly repaired tire can fail suddenly at a later date. Never repair a tire with less than 2/32nds of an inch tread remaining. At this tread depth, the tire is worn out and must be replaced.
Tires should be stored in a cool place away from direct sunlight, sources of heat and ozone such as hot pipes and electric generators. Exposure to these elements during prolonged periods of time will exhaust the tire's oxidation and weathering agents within the rubber compounds and result in cracking. Be sure that surfaces on which tires are stored are clean and free from grease, gasoline or other substances that could deteriorate the rubber. For mounted tires inflate at, but no higher than, the recommended air pressure. Store vehicle on blocks to remove load from the tires.
Service life for passenger car and light truck tires including spare tires
4 The following recommendation applies to passenger car and light truck tires. Tires are composed of various types of material and rubber compounds, having performance properties essential to the proper functioning of the tire itself. These component properties evolve over time. For each tire, this evolution depends upon many factors such as weather, storage conditions, and conditions of use (load, speed, inflation pressure, maintenance etc.) to which the tire is subjected throughout its life. This service-related evolution varies widely so that accurately predicting the serviceable life of any specific tire in advance is not possible. That is why, in addition to regular inspections and inflation pressure maintenance by consumers, it is recommended to have passenger car and light truck tires, including spare tires, inspected regularly by a qualified tire specialist, such as a tire dealer, who will assess the tire's suitability for continued service. Tires which have been in use for 5 years or more should continue to be inspected by a specialist at least annually. Consumers are strongly encouraged to be aware not only of their tires' visual condition and inflation pressure but also of any change in dynamic performance such as increased air loss, noise or vibration, which could be an indication that the tires need to be removed from service to prevent tire failure.
It is impossible to predict when tires should be replaced based on their calendar age alone . However, the older a tire the greater the chance that it will need to be replaced due to the service-related evolution or other conditions found upon inspection or detected during use. While most tires will need replacement before they achieve 10 years, it is recommended that any tires in service 10 years or more from the date of manufacture, including spare tires, be replaced with new tires as a simple precaution even if such tires appear serviceable and even if they have not reached the legal wear limit. For tires that were on an original equipment vehicle (i.e., acquired by the consumer on a new vehicle), follow the vehicle manufacturer's tire replacement recommendations, when specified (but not to exceed 10 years).
The date when a tire was manufactured is located on the sidewall of each tire. Consumers should locate the Department of Transportation or DOT code on the tire which begins with DOT and ends with the week and year of manufacture. For example, a DOT code ending with "2218" indicates a tire made in the 22nd week (May) of 2018.
The right tire for the season - Passenger and light-truck
Different types of tires provide unique performances that are delivered by specific technical solutions including mold design, construction and materials. All BFGoodrich tires meet or exceed federal regulations.
We therefore recommend the following:
- Summer tires are designed to perform best in warm weather conditions. Summer tires should be removed when ambient temperatures are consistently below 7°C.
- All Season tires are designed to provide optimized performance in warm weather conditions as well as a reliable performance in moderate winter conditions. All Season tires should be replaced by winter tires on all wheel positions during severe winter conditions (when temperatures are consistently below the freezing point and/or there are regular winter precipitations such as snow or freezing rain).
- Winter tires are designed to perform best in cold weather during severe winter conditions. Winter tires should be removed when ambient temperature is consistently above 7°C.
Who do I contact about a career with BFGoodrich?
Where can I obtain pricing information?
Our passenger and light truck tires are sold through our network of retailers. We do not sell direct to the public.
The selling retailer establishes pricing on tires. For pricing on our tires please contact your local participating dealer. A listing of dealers can be found by utilizing the Dealer Locator link on bfgoodrichtires.ca or in your local Yellow Pages under the category – Tire Dealers Retail.
Can I mix different speed-rated tires on my car?
If tires of different speed ratings are mounted on a vehicle, the lower speed-rated tires should be placed on the front axle. This is to prevent a potential oversteer condition. Vehicle handling may be affected, and the vehicle’s speed capacity is now limited to the lowest speed-rated tire.
Can I mix tire types on my car?
For best all-around performance, the same type tire should be used on all four-wheel positions. Tires of different size designations, constructions, and stages of wear may affect vehicle handling and stability. NOTE: Some vehicles are intentionally fitted with different size tires on front and rear. For four-wheel drive vehicles, if no instructions for tire mixing appear in the vehicle owner’s manual, adhere to the following guidelines:
- Do not mix sizes. All four tires must be branded with the same tire size.
- Be sure that the outside circumference of all four tires is within 5/32” of each other.
- Do not mix tread patterns, such as all-terrain and all-season.
Can I replace the tires on my car with a lower speed-rated tire?
When replacing speed-rated tires, you must use replacement tires with ratings equal to or greater than those of the original equipment tires, if the speed capability of the vehicle is to be maintained. The handling of a performance vehicle may be different when the replacement tires are not the same speed rating. Refer to the vehicle owner’s manual to identify any tire speed rating restriction that could affect operation of the vehicle.
Do I have to replace my present tires with the same size tires?
Never choose a tire that is smaller in size or has less load-carrying capacity than the tire that came with the vehicle. Tires should always be replaced with the same size designation — or approved options — as recommended by the vehicle or tire manufacturer. The correct tire size can be found on the door placard of the vehicle or by consulting your local authorized BFGoodrich Tire dealer. (You can find a dealer near you by using the Dealer Locator) Your current tires’ size can be found by reading the markings on the sidewall.
Where do I install new tires if I only buy two?
If you’re replacing only two tires, be sure to have the new tires installed on your vehicle’s rear axle. Here’s why:
- New tires will provide better wet grip than your half-worn tires.
- When new tires are installed on the rear, it helps reduce the potential for your vehicle to fishtail or hydroplane in wet conditions.
Is my damaged tire covered by a BFGoodrich Tires warranty?
Quite possibly. Take the tire to your local authorized BFGoodrich Tire dealer and have them properly inspect the tire. Tell the dealer what you are experiencing so they can diagnose the problem.
What should I do if I notice a vibration?
Vibration is an indication that your car has a problem that needs attention. The tires, steering system and suspension system should be checked to help determine the possible cause and correction of the vibration. If left unattended, the vibration could cause excessive tire and suspension wear. It could even be dangerous. Authorized Dealers offer expert diagnosis and repair.
Are punctures/cuts covered under the warranty?
Our warranty covers defects in workmanship and material for the life of the tread or 6 years, whichever comes first. We do not cover tires that are damaged as a result of road hazards, cuts, punctures, impact, etc.
Some retailers offer extended policies for road hazard injuries in addition to the manufacturer’s warranty. Refer to your original sales receipt to see if such coverage applies.
What are the causes of center tread wear?
When the center tread wears faster than the adjacent tread surfaces, possible causes include over inflation for load carried, rim width too narrow, misapplication, smooth wear after spin-out, improper tire rotation practices, aggressive acceleration or under inflation for certain tire types, such as performance tires.
If the tread depth is at or below 2/32" in any groove or if cord material or under tread is exposed, the tire must be replaced. If sufficient tread remains, verify proper rim width and vehicle fitment as well as verify/adjust inflation pressures, then rotate the tires for maximum wear.
Is a Bubble/Bulge on the sidewall of my tire covered by your warranty?
A bulge or bubble in the sidewall is sometimes the result of damage from coming in contact with a curb, pothole or other object. Evidence of this damage can be:
- a scuff mark on the sidewall near the bubble
- a dent or damage on the wheel above the bulge
- a cut or bruise on the inner liner of the tire in the vicinity of the bulge (the tire must be demounted in order to inspect the inner liner)
A tire that sustains any of the above injuries is damaged and is not covered under warranty.
However, your satisfaction is important to us and we request that you take the tire into a participating dealer for inspection to determine if warranty coverage applies.
What are road hazard injuries?
Road hazard damage is damage that occurs when a tire fails as a result of a puncture, bruise or break incurred during the course of normal driving on a maintained road. Nails, glass and potholes are the most common examples of road hazards.
Avoid running over objects (e.g. chuckholes, rocks, curbs, metal, glass, etc.) which may cause internal tire damage. Internal damage, not visible without demounting the tire, may be caused when a tire runs over an object. Continued use of a tire that has suffered internal damage (which may not be externally visible) can lead to dangerous tire failure. Determination of suspected internal damage requires demounting the tire from its rim and examination by a trained tire personnel.
What can cause my tire to show One-Sided Shoulder Wear?
When the shoulder of the tread on one side of a tire wears faster than the adjacent tread surface, this can result from a variety of conditions, such as front and/or rear misalignment (example, toe or camber), loose or worn suspension components, hard cornering, improper tire rotation practices, misapplication, high crown roads or non-uniform mounting.
If the tread depth is at or below 2/32" in any groove or if either cord or under tread is exposed, the tire must be replaced. If sufficient tread remains, verify that the tire has been properly mounted, then rotate the tires for maximum wear.
What can cause my tire to wear in more than one spot around the circumference?
When tread is worn in one or more spots around the tire circumference, this can indicate brake lock/skid, improper balance, localized underlying separation, loose/worn suspension components, improper bead seating/mounting, progression from initial tread cut/chip/road hazard injury or chemical contamination. Surface texture may have initially shown abrasion marks from the tire sliding on the road, but the surface may have since worn smooth.
When the tires with a flat spot are used in a dual application. you may consider rotating one tire 180 degrees in relation to the flat spot on the other tire.
If the tread depth is at or below 2/32" in any groove or if either cord or under tread is exposed, the tire must be replaced.
When the cause of the flat spot is not apparent, your tire dealer should contact our Consumer Care Department.
What can cause my tire tread face to show one rib higher than the other?
Feathering is a condition when the edge of each tread rib develops a slightly rounded edge on one side and a sharp edge on the other. The most common causes of feathering are incorrect toe-in setting or deteriorated bushings in the front suspension. The toe setting should be as close to 0 as possible for the optimum wear.
The tires should be inflated to the pressure as indicated on the sticker on the inside of the driver’s door. The vehicle manufacturer has determined this pressure is optimal for load, ride, handling, rolling resistance and tread wear performance.
What can cause the sidewall of my tires to start turning a brownish color?
The brownish color on the sidewall of your tires is not a defect. The source of this discoloration can be varied. One possibility is that the tires contain an anti-ozone agent in their rubber compounds to slow down the ill effects of exposure to ozone in the air. This anti-ozone ingredient will migrate to the surface of the rubber and leave the appearance of a brownish dust. This is completely normal and technically is no cause for concern. In time, depending on usage, it will disappear.
Other possibilities for discoloration can be simply dust that is picked up from normal driving or brake dust which is generated by the abrasion of the brake pads against the brake rotor. This latter condition is more prevalent when the brakes are new or have recently been relined. In all cases, we recommend that you continue to clean your tires with a mild soap and water.
What causes a tire to wear out?
Treadwear or life expectancy is determined by many factors:
Driving habits and style of driving, geographical location, type of vehicle, type of tire, how vehicle is maintained, how tires are maintained, etc.
As a result, mileage expectancy is impossible to determine.
Our Limited Warranty covers defects in workmanship and material for the life of the tread or 6 years from the original date of purchase, whichever occurs first. We offer no mileage warranty on the tires that were originally equipped on your vehicle.
We suggest that you have the tires/vehicle inspected by a participating tire retailer in your area to determine if there is perhaps a mechanical or maintenance issue that could be contributing to a rapid or irregular wear pattern.
Your satisfaction is important to us. Please have the dealer contact us with the tire inspection as we are willing to offer you assistance with your concern.
What causes sidewall Indentations on my tire?
The condition, sometimes referred to as sidewall undulations, is a common characteristic of radial tire construction and are purely a visual characteristic and will not affect the performance of the tire. These indentations are more noticeable in larger/wider radial-ply tire sizes and become more visible with higher inflation pressures. The joining of the ply material in the sidewall area may cause a slight indentation or wavy appearance on the sidewall surface of the tire when it is inflated. However, if bulges, rather than indentations appear on the sidewall of the tire, or if there is any question concerning any sidewall indentations, please contact a tire dealer for a tire inspection
What could be the cause of my tires making a loud noise?
Noise is most commonly due to an uneven or irregular wear pattern that has developed on the tires.
We suggest that you have the tires inspected by a participating tire retailer in your area. To find the dealers near you, refer to the Yellow Pages or utilize the Dealer Locator on our website
What could cause my tire to wear on the Inside and outside shoulders?
The cause of Inside and Outside shoulder wear is normally due to improper inflation pressure, hard cornering, frequent mountain driving, improper tire rotation practices or a rim width too wide for the tire. Commercial delivery service vehicle tires frequently experience this type of wear pattern.
If the tire's tread depth is at or below 2/32" in any groove or if cord material or under tread is exposed, the tire must be replaced. If sufficient tread remains, verify proper rim width and vehicle fitment as well as verify/adjust inflation pressures, then rotate the tires for maximum wear.
What could cause my tire tread to come off?
A separation between the tread rubber and the underlying belt may be the result of cumulative poor inflation maintenance, improper inflation pressure, repair or storage, excessive load, speed or heat, prior impact damage, tread cut or puncture or run flat.
A tire exhibiting this condition should be permanently removed from service.
What does it mean if my tire has shredded into pieces?
The tire industry refers to tires in this condition as "run flat" which refers to a tire that has lost air, whether it is from a slow loss or an immediate loss, and then subsequently run on. As the tire continues to operate or "run" with significant amount of air loss, it reaches the "runflat" stage, where serious internal damage is caused by the excessive deflection of the casing. If the air loss continues, the inside of the deflected sidewall can actually rub against itself. When the internal abrasion weakens the casing sufficiently a blowout can occur. Additional damage is often done by the relatively sharp rim flange cutting into the fully deflated casing as it is driven after the blowout, even in the short distance it takes to drive the vehicle to the side of the road.
We are not indicating that the tire was not maintained, but simply that it lost air. Some of the many factors which can cause a tire to lose its inflated air pressure are penetrations, cuts, snags, impact breaks, valve stem leaks, incorrect mounting, just to name a few. While it may not be possible to pinpoint the cause of initial air loss, we know the outcome is underinflation damage.
What does it mean when my tires start to show signs of Aging, ozone cracking or weather cracking?
The life of a tire cannot be measured by miles alone. Tires are composed of various types of material and rubber compounds, having performance properties essential to the proper functioning of the tire itself. These component properties evolve over time. For each tire, this evolution depends upon many factors such as weather, storage conditions, and conditions of use (load, speed, inflation pressure, maintenance etc.) to which the tire is subjected throughout its life. This service-related evolution varies widely so that accurately predicting the serviceable life of any specific tire in advance is not possible.
It is impossible to predict when tires should be replaced based on their calendar age alone. However the older a tire the greater the chance that it will need to be replaced due to the service-related evolution or other conditions found upon inspection or detected during use.
While most tires will need replacement before they achieve 10 years, it is recommended that any tires in service 10 years or more from the date of manufacture, including spare tires, be replaced with new tires as a simple precaution even if such tires appear serviceable and even if they have not reached the legal wear limit.
The warranty covers defects in workmanship and material for the life of the tread or 6 years from the date of purchase, whichever occurs first. With no proof of purchase, the warranty period is for 6 years from the date of manufacture (this is indicated in the DOT # on the sidewall).
What is Cupping?
Cupping can be attributed to bent or worn suspension parts, wheel misalignment, an imbalance of the tire/wheel assembly, etc. Once this type of wear pattern has occurred, it is irreversible and the tires will continue to wear unevenly.
What should I do if my vehicle is pulling to one side?
Incorrect alignment settings can adversely affect handling. Tolerable camber, caster and toe settings can be verified by a print-out from your alignment/tire shop or vehicle dealer.
If the tires are evenly worn, the alignment is in order and there is still a pull, the front tires should be criss-crossed (as long as they are not a directional tread design) to see if the pull changes directions.
This should be performed by a participating dealer.
What should I do if the cords on my tires are visible?
Cord material may become visible at the base of tread grooves or slots due to under inflation, misalignment, loose/worn suspension components, hard cornering, improper tire rotation practices, misapplication, high crown road or non-uniform mounting.
If cord material is visible, the tire must be replaced
What should I do if my tires wore too fast?
An inspection of your tires must be performed by a participating BFGoodrich Tire dealer. Once the dealer has had the opportunity to inspect your tires, inform them that you have been instructed by BFGoodrich Tires to request that they contact us at the 1-877-788-8899 to discuss their findings "while you are there".
Factors that can affect rapid tire life are:
- tire maintenance (inflation and rotation)
- vehicle maintenance (alignment and suspension)
- driving styles and habits
- materials used in road surfaces
- topography of the area the vehicle is driven in.
Can you elaborate on why winter Tires have no Uniform Tire Quality Grade rating?
Winter tires are designed for cold weather use only, usually when average daily temperatures are consistently approach freezing. While the tire operates just fine in warmer conditions,it is not recommended for summer usage.
Treadwear and temperature ratings are not primary attributes for winter tires and usage is regional..
What is a Directional tread design?
Tires with directional tread patterns must be mounted so that the forward direction of rotation matches the directional arrows on the tire sidewall. If all four tires are the same size, directional tires can be rotated front to back.
Tires with tread patterns that are both asymmetric and directional require left and right specific tires. Sidewall markings will identify the side of the vehicle and the primary direction of rotation for the tire. If all four tires are the same size, they can be rotated front to back
What is Excessive Spinning?
Excessive wheel spinning, when freeing a vehicle from sand, mud, snow, gravel, ice or wet surfaces, can result in explosive tire failure, causing serious personal injury or vehicle damage. Do not exceed 35 MPH (55km/h), as indicated on the speedometer. Never stand near, or behind, a tire spinning at high speeds when attempting to push a vehicle that is stuck.
How much load/weight can my tire carry?
Never exceed the load-carrying limits molded on the sidewall of the tires or the maximum vehicle axle load limit as shown on the vehicle tire placard, whichever is less. Overloading builds up excessive heat in the tire and could lead to failure.
What is a Speed rating?
The speed rating of a tire indicates the speed category (or range of speeds) at which the tire can carry a load under specified service conditions. The speed rating system used today was developed in Europe in response to the need to categorize tires into standardized speeds. A letter from A to Z symbolizes a tire's certified speed rating, ranging from 5km/h (3 mph) to above 300 km/h (186 mph).
content speed rating 346
What guidelines should I follow when mixing tires on 4WD vehicles?
If no instructions for tire mixing appear in the vehicle owner’s manual, adhere to the following guidelines:
- Do not mix sizes. All four tires must be branded with the same tire size.
- Be sure that the outside circumference of all four tires is within 5/32 of each other.
- Do not mix tread pattern types such as all-terrain and all-season.
Can I go to a lower speed rated tire than what came on the vehicle?
It is recommended that the replacement tire size speed rating be equal to or higher than that of the O.E. tire size speed rating. If a lower speed rated tire is selected, then the vehicle top speed becomes limited to that of the lower speed rating selected. The customer must be informed of the new speed restriction. It is quite common and permissible during winter driving to use a winter tire with a lesser speed rating than the O.E. tire. Again the customer must be informed as mentioned above.
Can I use my summer tires in winter?
No. These tires are specifically designed for warm weather use. Winter tires are designed for cold weather use only, usually when average daily temperatures are consistently approach freezing.
Do you recommend Used tires?
Avoid used tires - you can never know what hazards and abuse a previously owned tire has suffered. Internal damage can lead to dangerous tire failure.
Do you support Plus Sizing?
Please remember, Plus Sizing must be taken with proper care. When replacing tires with optional size designations, be sure to check vehicle manufacturer’s recommendations (found in owner’s manual or on door sticker). Interchangeability is not always possible because of difference in load ratings, tire dimensions, wheel well clearance and rim size.
However, if you can provide the original equipment tire size and the tire size you wish to install, we can provide the tire specifications and differences.
If you need assistance locating a participating tire retailer, refer to the Yellow Pages or the Dealer Locator.
How do I determine if my current rim is approved for your tires?
The rim width range is extremely important. This range represents proper rim widths that will assist the tire/wheel assembly in meeting its performance potential. To achieve the best balance between ride, handling and tread wear, select a rim width in the middle of the manufacturer’s range.
To improve cornering traction and steering response, choose a rim at or near the maximum recommended width. The wider the rim width, the straighter the sidewall and the quicker the steering response. Conversely, using a rim width at the low end of the range will cause the tire to balloon or curve out, slowing steering response.
Refer to our website for tire specifications
How is the overall tire diameter measured?
A tire is mounted on the appropriate rim width as identified by T&RA or ETRTO then inflated to 1.8 bar (26 psi). A calibrated measurement tape is run around the circumference of the tire in the center of the tread (which represents the largest overall diameter). This measurement of circumference is then divided by the mathematical constant known as PI (3.14126...) to calculate the diameter.
How to read the DOT number?
DOT signifies that the tire complies with the United States Department of Transportation tire safety standards, and is approved for highway use.
DOT M5H3 459X 2318 (This indicates the tire was manufactured the 23rd week of 2018)
The first two digits following DOT designate the tire's manufacturer and plant code. The third and fourth characters denote the tire size. The fifth, sixth, seventh and eighth (optional) characters identify the brand and other significant characteristics of the tire. The ninth and tenth characters denote the week the tire was produced. The final number(s) signifies the year in which the tire was manufactured.
How to read the sidewall of my tire?
The side of a tire contains information needed for your safety and that of your customer. Being able to read sidewall markings will help you better understand the performance of each tire. It will also provide you with information when mounting and servicing the tire.
Passenger Tire Sizing
Three primary sizing systems exist for passenger tires today: P-Metric, European Metric and Millimetric. Each of these systems evolved from the first tire sizing system-the Numeric Sizing system-that is now obsolete. It was developed when all tires had the same aspect ratio, and it provided only the nominal cross section width of the tire and the rim diameter in inches. The following are examples that identify the three sizing systems that are commonly seen today.
- P-Metric - The P-Metric sizing system was developed to better align with the European tire sizing system. It provides a better description of the tire size. See examples below.
- European Metric - Essentially, this system was a conversion of the Numeric system from inches to millimeters. Aspect ratio appears in the size designation in most cases where it is other than 82.
- Light Truck Tire Sizing - Sizing for light truck tires takes the performance requirements of the vehicle, and the tires, into account. Light truck tires have evolved along with the expanded applications of trucks and vans that have grown to be multi-purpose vehicles that we use for work, for recreation or as passenger vehicles. There are three primary light truck tire sizing systems: Light Truck Metric, Light Truck High Floatation and Light Truck Numeric.
- Light Truck Metric - This sizing system mirrors the P-Metric system for passenger tires.
- Light Truck High Flotation - Light truck high flotation tires have evolved as lower aspect ratio tires became more popular on light trucks. The combination of lower aspect ratios and high flotation yielded better traction on sand and soft soil found in off-road situations.
- Light Truck European Commercial Metric - This size system mirrors the European Metric system for passenger tires and is intended for commercial light truck vehicles sometimes referred to as “Euro Vans”. Often these tires are referred to as European C-Type sizes.
- Light Truck Numeric - This older system is still widely used, mostly on commercial vehicles.
What is difference between P-metric and metric?
P-metric sized tires are those with the "P" at the beginning of the tire size (such as P215/65R16). P-metric sizes were introduced in the United States in the mid 70s and are installed on vehicles primarily used to carry passengers including cars, station wagons, sport utility vehicles and even light duty pickup trucks. Their load capacity is based on an engineering formula which takes into account their physical size (the volume of space for air inside the tire) and the amount of air pressure (how tightly the air molecules are compressed). Since all P-metric sizes are all based on the formula for load, vehicle manufacturers can design their new vehicles (weights and wheelwell dimensions) around either existing or new tire sizes.
Metric or Euro metric sized tires are the ones without the "P" at the beginning, (such as 215/65R16). Using metric dimensions to reflect a tire's width actually began in Europe in the late 60s. However, since Euro metric sizes have been added over time based on the load and dimensional requirements of new vehicles, the tire manufacturers designed many new tire sizes and load capacities around the needs of new vehicles. Not quite as uniform as creating sizes using a formula, but they got the job done.
Euro metric and P-metric tires in the same size (i.e. P215/65R16 and 215/65R16) are equivalent in their dimensions with just slight differences in their load capacity calculations and inflation pressure tables.
Where are your tires manufactured?
Our strategy is to manufacture tires in the country where they will be sold whenever possible. In fact, the vast majority of our products sold in North America, are built in the 21 plants we have across the United States, Canada and Mexico, employing most of the 23,000 employees of Michelin North America, Inc. However, we are an international company, with manufacturing operations at 74 plants across 19 countries around the world. To meet the needs of our customers by providing more specialized tire lines in smaller quantities, we import some tire lines into North America and we export others from North America.
Please be assured that no matter where your tires are manufactured, they are built to the standards that have made our products the benchmark for the industry.
Where can I find the DOT on my tire and what does it signify?
The "DOT" symbol certifies the tire manufacturer's compliance with the U.S.Department of Transportation tire safety standards. Tires manufactured for use in the United States have the full DOT serial number located on one sidewall near the rim. A partial DOT serial number will appear on the opposite side of the tire.
How long should my original equipment tires last?
We do not offer a written mileage warranty on any tires supplied as original equipment. Due to the variety of styles, construction features, tread compounds, vehicle applications, geographical conditions and driving habits, it is difficult to provide a specific mileage expectancy.
However, any tire wear concern should always be presented to your local authorized dealers for further evaluation.
Many of our authorized retailers offer specific mileage warranties on several lines of tires sold as replacement tires, including some tires that are used as original equipment. These mileage warranties are administered based on the retail outlets verification of proper tire maintenance having been performed.
How should I care for tires I have in storage?
Tires should be stored in a cool place away from direct sunlight, sources of heat and ozone such as hot pipes and electric generators. Exposure to these elements during prolonged periods of time will exhaust the tire's oxidation and weathering agents within the rubber compounds and result in cracking. Be sure that surfaces on which tires are stored are clean and free from grease, gasoline or other substances that could deteriorate the rubber.
For mounted tires inflate at, but no higher than, the recommended air pressure. Store vehicle on blocks to remove load from the tires.
Can I mount my own tire on the wheel?
Never try to mount your own tires. Tire mounting is a job for trained professionals who have the proper equipment and experience. If you try to do it yourself, you run the risk of serious injury to yourself as well as possible damage to the tire and rim.
