Never mix and match tires with different speed ratings on your vehicle

Speed Ratings

A tire receives its speed rating by the U.S. Government through meeting minimum standards for reaching and sustaining a specified speed. What does that mean to you? Well, in general, a higher speed rating will result in better car handling.

Two important notes when considering speed rating:
  • We do not recommend downgrading the speed rating of your tires. This may result in poor handling and unpredictable steering. However, if you want better cornering response, there is no problem installing a higher speed rated tire on your vehicle.
  • Never mix and match tires with different speed ratings on your vehicle. This will cause serious problems with the handling of your vehicle.

Below is a list of speed ratings along with the corresponding speeds they represent. Remember, the speeds are test speeds, not recommended speeds.
