Finding your Speed Rating
The best place to find your Speed Rating is on the vehicle itself. Do not rely on websites or even your vehicle's owner's manual to determine your vehicle's recommended speed rating.

First, find your vehicle load and tire information placard. This placard is usually located on the door jamb of the driver's door. See an example of this placard in the picture to the right.

Now, look for the tire size information on your placard. The speed rating is generally written after tire size and load rating. In the example to the right the speed rating is "S". (Note that the "S" written immediately after the "99" in the red box.)

Valid speed ratings are H, Q, S, T, U, V, W, Y, and Z.
