If you see any damage to a tire or wheel, replace it with the spare at once and visit a participating Tire Retailer. Exceeding the maximum speeds shown on the following page for each type of tire will cause the tire to build up excessive heat which can cause tire damage that could result in sudden tire destruction and rapid air loss. Failure to control a vehicle when one or more tires experience a sudden air loss can lead to an accident. In any case, you should not exceed reasonable speeds as indicated by the legal limits and driving conditions. SPEED RATINGS Speed Symbols are shown on the sidewall of some tires. The following table shows the maximum speed corresponding to the symbol. *Some V (or VR) rated tires may have a speed capacity greater than 149 mph (240 km/h). Consult your tire retailer for maximum speed rating if your vehicle capability exceeds this speed. **Z (or ZR) rated tires are designed to use on cars with maximum speed capabilities in excess of 149 mph (240 km/h). (W and Y speed ratings are sub-categories of Z). Consult your tire retailer for maximum speed capabilities. Although a tire may be speed-rated, we do not endorse the operation of any vehicle in an unsafe or unlawful manner. Speed ratings are based on laboratory tests which relate to performance on the road, but are not applicable if tires are underinflated, overloaded, worn out, damaged, altered, improperly repaired, or retreaded. Furthermore, a tire's speed rating does not imply that vehicles can be safely driven at the maximum speed for which the tire is rated, particularly under adverse road and weather conditions or if the vehicle has unusual characteristics. Highway passenger tires that do not have a speed symbol on the sidewall have a maximum speed rating of 105 mph (170 kph). Light truck highway tires that do not have a speed symbol on the sidewall of the tire have a maximum speed rating of 87 mph (140 kph). 55
