Speed Rating

Speed Rating – All about safety

Stay safe! Tire speed rating indicates the maximum service speed for a tire. So, exceeding speed limits is not recommended by the tire manufacture. In addition, no indicator exists for how well the tire handles or corners.

This rating provides a maximum speed capability of the tire with proper inflation. Manufacturers do not recommend fitting tires with different ratings. Doing so could lead to poor handling and unpredictable steering. If a vehicle has tires with different ratings, then placing like pair tires on the same axle is ideal. Otherwise, the speed capability of the vehicle is determined to be that of the lowest speed rated tires.

Letters ranging from L to Z identify the speed rating. The lowest rating, L,  is 75 mph. The highest rating, Z, is 149+ mph. For more speed limits, please refer to speed rating Chart below for more detail.

Please note that this is the speed rating chart example used for instructional purposes. Our goal is to help you understand this rating system. So, please refer to your tire’s specifications.
