Tire Speed & Load
Speed Rating

Tire speed rating tells you the maximum service speed for a tire. A speed rating isn't, however, a recommendation to exceed speed limits, and doesn't indicate how well a tire handles or corners.

Generally, it is recommended that a speed-rated tire be replaced with a tire having an equivalent or greater speed rating. For example, if the recommended speed rating is a V, it's suggested that you replace it with a V, W, Y, or Z

It is not recommended to fit tires with different speed ratings. If tires with different speed ratings are installed on a vehicle, they should be installed with like pairs on the same axle. The speed capability of the vehicle will become limited to that of the lowest speed rated tires. Obey all speed limits.

** Per the TR&A 2007 yearbook, for tires having a maximum speed capability above 240 km/h (149 mph), a ZR may appear in the size designation. For tires having a maximum speed capacity above 300 km/h (186 mph), a ZR must appear in the size designation and a service description, including the Y speed symbol, must be included in brackets.
