Avon Speed Capability
The speed capability of the replacement tires must always equal or exceed the original equipment tires.
When replacing tires, consult the placard (normally located on a door frame, door edge, or glove box door) or the owner's manual for correct size. If the tires shown on the vehicle placard do not have speed ratings, the appropriate size tire with any speed rating may be applied.
When the placard tire size contains a speed symbol, for example P205/60HR15 or P205/60R15 90H, the replacement tire must have the same or higher speed rating symbol if the speed capability of the vehicle is to be maintained. If the replacement tire is not speed rated, the speed capability of the vehicle is limited by the speed capability of the replacement tire. A Cooper-produced non-speed rated passenger tire's maximum speed is 85 mph (137 km/h).
Speed Category S 180 km/h (112 mph) T 190 km/h (118 mph) U 200 km/h (124 mph) H 210 km/h (130 mph) V 240 km/h (149 mph) *W 270 km/h (168 mph) *Y 300 km/h (186 mph)
Cooper's speed symbol designations in this table are based upon indoor wheel tests conducted in accordance with the Procedure for Load/Speed Performance Tests of the Economic Commission for Europe (ECE-30).
* For tires having a maximum speed capability above 240km/h (149 mph), a "ZR" may appear in the size designation.
Tire Designation Maximum Speed P275/40R17 93W 270 km/h (168 mph) P275/40R17 93Y 300 km/h (186 mph) P275/40ZR17 93W 270 km/h (168 mph) P275/40ZR17 93Y 300 km/h (186 mph)
While a speed symbol is an indication of the speed capability of the tire, we do not endorse the operation of any vehicle in an unsafe or unlawful manner.
