What is the speed rating t on a tire?

The speed rating "T" on a tire indicates the maximum speed the tire can safely sustain under optimal conditions. Specifically, a tire with a "T" rating is rated for speeds up to 118 mph (190 km/h). This rating helps ensure that the tire performs well and maintains safety at higher speeds, making it important for vehicle performance and safety considerations. Always consult your vehicle's manual to ensure you are using tires with appropriate speed ratings.
