Tire Speed Rating Chart

Chart of tire speed ratings and corresponding speeds they represent.



Tire speed rating indicates the maximum service speed for a tire.

Tire speed rating is found on the sidewal of your tire as a part of tire size service description.

Tires can have different speed ratings, so it is important to choose the tire that is best suited for your vehicle. It is recommended to choose new tires with a speed rating at least equal to your old tires. If you mix tires with different speed ratings, make sure you observe the lowest speed rating.

Tire speed rating is not a recommendation to exceed speed limits.
