Find Your Tire Speed Rating

What is a Tire Speed Rating?

A Tire Speed Rating indicates the maximum speed capability or limit at which your tire was designed to perform. Although the speed rating indicated the max speed capability of the tire, this number does not imply that the tires can be driven on safely at it's maximum speed, especially in harsh road conditions.

Where can I find my Tire's Speed Rating?

In most vehicles, a Tire's Speed Rating can be found in:

  • Vehicle's Owner Manual
  • Driver's Side Door Jam
  • Glove Box Door
  • Gas Tank Hatch

You can also possibly find the speed rating of your vehicle on the sidewall of your tire at the end of the tire size. As an example: if your tire size is "225/70R16 91S", the "S" at the end is the speed rating. Speed ratings are rated A-Z. "A" would indicate the lowest speed category where "Z" would indicate the highest speed category.
