120 I Tire Technologies Important Product Information Following these basic product specs and mounting guidelines will ensure safety for both the driver and the service technician. Passenger sizes used in Light Truck/SUV/Crossover applications have reduced load capacity. This will differ from the maximum load indicated on the tire sidewall. Government UTQG Ratings do not apply to light truck-sized tires. Government UTQG Ratings do not apply to winter tires. 1. The dimensions shown are average tire 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. 2. Section width varies approximately 0.2" (5 mm) 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. 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 tires having a maximum speed capability above 149 mph, a "ZR" may appear in the tire designation. For tires having a maximum speed capability above 186 mph, a "ZR" must appear in the size designation. Consult the tire manufacturer for the tire's maximum speed capability when there is no Service Description or when the Service Description is stated in parentheses. Example: TIRE DESIGNATION P275/40ZR17 P275/40ZR17 93W P275/40ZR17 93Y P275/40ZR17 (93Y) MAXIMUM SPEED Above 149 mph, consult the tire manufacturer. 168 mph 186 mph Above 186 mph, consult the tire manufacturer. For high-speed driving, additional inflation pressure and possibly reduced tire loading and/or upsizing are 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 Organisation Standards Manual.
