Government UTQG Ratings do not apply to light truck sized tyres.
>> The sizes shown are average design values for tyres measured on specified measuring rim widths. Some tyres 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.
>> Tread patterns are often tuned to accommodate different tyre widths. Tyres for a particular dimension of a given tyreline may vary in appearance from the tyre shown in the photograph.
WARNING: Serious or fatal injury may result from tyre failure due to underinflation or overloading. To ensure correct air pressure and vehicle load, refer to vehicle owner's manual or tyre information placard on the vehicle. Serious injury or death may result from explosion of tyre/rim assembly due to improper mounting. Only tyre professionals should mount tyres and they should never inflate beyond 40 psi to seat the beads. Before mixing types of tyres in any configuration on any vehicle, be sure to check the vehicle owner's manual for its recommendations. No tyre is indestructible. An impact can cause a tyre to fail, resulting in serious injury or death. Consult your tyre owner's manual for proper maintenance instructions.
When replacing an Original Equipment P-Metric or Euro Metric size tyre with an LT-metric or High Flotation size tyre, the air pressures of the LT-metric / High Flotation tire must be adjusted in order to properly carry the load of the vehicle. See your BFGoodrich Tires dealer for the proper air pressure recommendation.
DANGER: Never mount a 16" diameter tire on a 16.5" rim.
DANGER: Never mount a 17" diameter tire on a 17.5" rim.
Inflation pressure increase must not exceed the maximum pressure branded on the tire sidewall. When a customer requests a replacement tire with a lower speed rating than the original equipment tire, you must clearly communicate to him or her that the handling of the vehicle may be different, and that its maximum speed capability is limited to that of the lowest speed-rated tire on the vehicle. Exceeding the lawful speed limit is neither recommended nor endorsed.
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 160km/h (100 mph), load and inflation must be adjusted according to the table below.
