>> The sizes shown are average design values for tires measured on specified measuring rim widths. Some tires may vary from this value by +/-3% of the section height (affecting overall diameter), and +/-4% of the section width.
>> Section width varies approximately 0.2" (5mm) for every 0.5" change in rim width.
WARNING: Serious or fatal injury may result from tire failure due to underinflation or overloading. To ensure correct air pressure and vehicle load, refer to vehicle owner's manual or tire information placard on the vehicle. Serious injury or death may result from explosion of tire/rim assembly due to improper mounting. Only tire professionals should mount tires and they should never inflate beyond 40 psi to seat the beads. Before mixing types of tires in any configuration on any vehicle, be sure to check the vehicle owner's manual for its recommendations.
DANGER: Never mount a 16" diameter tire on a 16.5" rim.
DANGER: Never mount a 17" diameter tire on a 17.5" rim.
Important Note: The g-Force R1 is a special-use product designed for competitive racing. As such, the following precautions must be followed when using the product.
At the Race Track:
Never inflate the tire to less than 19 psi.
Use the information provided in the BFGoodrich g-Force R1 Care & Feeding Brochure for cold inflation pressure guidelines and other product usage recommendations
On the Street:
g-Force R1 tires have a reduced tread depth when new, and a tread rubber compound optimized for maximum dry grip. As such, they will wear out much sooner and offer less wet grip when compared to normal passenger-car tires. Therefore, observe tire-wear condition often. Do not use the tires on the street when the tread depth wears to less than 2/32nds inch. Reduce speeds in wet conditions and whenever any standing water is present. The g-Force R1 is not intended for use in snow and ice conditions.
For high-speed driving, additional inflation pressure and possibly reduced tire loading and/or upsizing is required. In the absence of specific recommendations by the vehicle manufacturer, use the following guidelines based on those in the European Tyre and Rim Technical Organization Standards Manual.
For speeds over 189km/h (118 mph), load and inflation must be adjusted according to the table below.
W-Speed Rated Sizes:
Maximum Speed (mph) 118 124 130 136 143 149 155 161 168
Inflation Increase (psi) 0 1.5 3.0 4.5 6.0 7.5 7.5 7.5 7.5
