(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 km/h).
