Tire speed rating is a tire code that indicates a tire's maximum sustainable speed. Tires with high speed ratings typically have superior handlingat legal speeds. The set of tires on a vehicle should have the same speed ratings for optimal performance. However, if tires with different speed ratings are mounted on the car, the lower rated tires should be placed on the front.
As shown in the graphic above, the tire speed rating is located to the right of the load index rating. The tire speed is listed on the sidewall using letters to represent different speeds. Below is a chart with common tire speed ratings.
