If you notice a vibration after installing a new set of BFGoodrich All-Terrain T/A KO3 tires, it does not necessarily mean there is a problem with the tire itself.
BFGoodrich utilizes a tight-fitting bead design to minimize bead unseating during low pressure off-road usage. This bead design means proper mounting and bead seating are especially important. A tire can be holding air and appear to be installed correctly while still needing additional attention to ensure the bead is fully and uniformly seated on the wheel.
In many cases, following the USTMA industry standard mounting procedure, including lubricating the bead seat area on the wheel and tire bead, can help address a vibration or ride disturbance after installation.

Why can a newly installed KO3 tire vibrate?
A vehicle can develop a vibration for many reasons, so the cause should always be properly diagnosed by a qualified tire professional.
When vibration begins immediately after new tires are mounted, one area a technician should check is how the tire bead is seated against the wheel.
The bead is the part of the tire that fits tightly against the wheel and helps create the air seal. BFGoodrich off-road tires are designed with a robust, tight-fitting bead to support the demands of off-road use.
Because the bead is intentionally stiff and secure, careful mounting is important.
During installation, the tire may make the familiar “pop” associated with the bead moving into position and may begin holding air. However, that alone does not always confirm that the bead has settled completely and uniformly into its intended position around the wheel.
Even a small seating irregularity can affect how smoothly the tire-and-wheel assembly rotates and may be experienced by the driver as vibration.
Proper bead lubrication is important
One of the most important parts of mounting a performance or off-road tire is using the proper approved bead lubricant in the appropriate areas of both the tire and wheel.
Proper lubrication allows the bead to move into its correct position as the tire is inflated.
For the BFGoodrich Terrain Family, technicians should follow the appropriate U.S. Tire Manufacturers Association (USTMA) tire mounting procedures and equipment manufacturer instructions.
The goal is not simply to get the tire onto the wheel and holding air. The goal is to achieve consistent bead seating around the complete circumference of the tire before balancing and returning the vehicle to the road.
Because tire mounting requires specialized equipment and training, these procedures should be performed by a qualified tire professional.
Why fully deflating and reinflating the tire matters
Another important step is to fully deflate and reinflate the tire after its initial beat seating, following the proper USTMA mounting procedure.
This additional step helps allow the tire bead to settle uniformly into position on the wheel.
It can be easy to overlook in a busy service environment. Once a tire is mounted, inflated and holding air, the natural next step may seem to be moving directly to balancing.
With tires that use a particularly tight bead construction, however, proper seating should be confirmed before the technician begins trying to correct a ride disturbance by adding or repositioning balance weights.
If the tire is not seated uniformly, balancing alone may not address the underlying cause of the vibration.
Why adding more balance weight may not solve the problem
Wheel balancing is still an important part of tire installation. A correctly balanced tire-and-wheel assembly helps distribute mass evenly as the assembly rotates.
But balance and bead seating are two different things.
If a tire is not uniformly seated on the wheel, repeatedly adding or moving balance weights may not resolve the ride disturbance. Before continuing to “chase” a balance reading, the technician should confirm that the tire has been properly mounted and seated.
For shops using road-force measurement equipment, improper seating can also influence the readings technicians see during diagnosis.
That is why the mounting process should be checked before assuming that an unusually high amount of corrective weight is the only solution.
Do aftermarket wheels affect KO3 balancing?
They can.
Aftermarket wheels vary considerably in their design, dimensions and available locations for balancing weights.
Original Equipment wheels are engineered for a particular vehicle application and have defined locations where balancing weights can be installed. Some aftermarket wheel designs do not provide the same locations for clip-on weights, requiring technicians to use adhesive weights elsewhere on the wheel.
That difference can make balancing more challenging in certain applications.
Aftermarket wheels may also require additional attention during mounting to confirm that the tire bead is uniformly seated.
If your KO3 tires are installed on aftermarket wheels and you are experiencing vibration, let your tire dealer know so that the wheel fitment, mounting, bead seating and balancing can all be evaluated together.
What should I do if my KO3 tires vibrate after installation?
If vibration began after your BFGoodrich All-Terrain T/A KO3 tires were installed, return to a qualified tire dealer and explain what you are experiencing.
Ask the technician to evaluate the entire tire-and-wheel assembly rather than simply adding more balancing weight.
In particular, the technician should verify that:
The tires are properly mounted according to applicable professional mounting procedures.
An approved bead lubricant was used appropriately during installation.
The bead is uniformly and completely seated around the wheel.
The tire has undergone the appropriate full deflate-and-reinflate procedure as part of seating.
The tire-and-wheel assembly is correctly balanced.
Any aftermarket-wheel characteristics that could affect mounting or weight placement have been considered.
Your dealer can contact BFGoodrich if additional technical assistance is needed.
Can this happen with other off-road or performance tires?
The need for careful mounting is not unique to one tire.
Off-road, ultra-high-performance and other specialized tires can use stiff bead or sidewall constructions to deliver the characteristics required for their intended applications.
Those same characteristics can make proper mounting technique especially important.
The BFGoodrich All-Terrain T/A KO3 is engineered for demanding on-road and off-road use. Correct installation helps ensure that the tire-and-wheel assembly can deliver the ride quality and performance it was designed to provide.
Does vibration mean my KO3 tire is defective?
Not necessarily.
Vibration can have several possible causes, including tire mounting, wheel balance, wheel condition, fitment and other vehicle-related factors.
When a vibration occurs immediately following tire installation, proper bead seating is one of the items that should be checked before reaching a conclusion about the tire.
A qualified tire professional can inspect the tire-and-wheel assembly and determine the appropriate next step.
Should I remount or rebalance my KO3 tires myself?
No. Tire mounting and balancing require specialized equipment, procedures and training.
If you are experiencing vibration, bring the vehicle to a qualified tire professional. You can also show your technician the BFGoodrich mounting and balancing video on this page, which explains why correct lubrication, bead seating and the deflate/reinflate procedure are particularly important with performance and off-road tires.
What should I tell my tire dealer?
You do not need to diagnose the problem yourself.
Simply explain:
“I’m experiencing a vibration after installing my BFGoodrich All-Terrain T/A KO3 tires. Could you verify that the beads are fully and uniformly seated and that the recommended mounting, deflate/reinflate and balancing procedures were followed?”
That gives the technician a useful starting point while allowing them to properly inspect the vehicle and determine the actual cause.
Get the performance your KO3 was designed to deliver

FAQ
Vibration at highway speeds can have several causes. If it began after the tires were installed, have a tire professional inspect the mounting, bead seating and wheel balance. Correctly seating the tire on the wheel should be confirmed before repeatedly adjusting balance weights.
Yes. A tire can hold air even if the bead has not settled completely and uniformly into its intended position on the wheel. This is one reason technicians should visually confirm correct bead seating and follow the complete mounting procedure.
BFGoodrich Terrain Family tires use tight-fitting beads to help prevent unseating, an important consideration when tires are used at reduced pressures during off-road driving.
No. Balancing addresses weight distribution within the rotating tire-and-wheel assembly. If the tire is not properly seated on the wheel, balancing alone may not resolve the ride disturbance.
As part of the applicable professional mounting procedure, fully deflating and reinflating the tire can help achieve proper, uniform bead seating. This should be performed by a qualified tire professional using appropriate equipment and procedures.
Certain aftermarket wheel designs can make mounting and balancing more challenging, including the differences in the available locations for installing balancing weights. If vibration occurs with aftermarket wheels, the technician should evaluate both the wheel and tire installation.
