T

The “T” speed rating for tires indicates that they are theoretically rated for speeds up to 190 km/h (118 mph). This rating is part of the tire’s service description, often included in the tire size designation. Here’s an example: “P220TR15”, where “T” represents the speed rating.

Speed ratings for tires are standardized and signify the maximum speed capability of the tire under optimal conditions. The next higher speed rating is “H,” indicating a higher speed capability, while the next lower speed rating is “S,” indicating a lower speed capability. It’s important to match the speed rating of the tire to the vehicle’s maximum speed capability to ensure safe and optimal performance.
