What is the maximum speed for a W rated tire?

The designation of a "W" rated tire indicates that it is engineered to safely operate at a maximum speed of 168 mph (270 km/h). This rating is a part of the tire’s speed rating system, which categorizes tires according to their capability to withstand heat and maintain performance under varying speeds.

The W rating is specifically assigned to tires that provide stability and performance even at high speeds, making them suitable for high-performance vehicles. Manufacturers conduct rigorous testing to ensure that tires with this rating can perform as expected at these elevated speeds, supporting the vehicle's dynamics and safety features.

In contrast, other ratings correspond to different maximum speeds, which are lower than the W rating, reflecting their purpose and design. Knowing these ratings helps consumers select appropriate tires for their driving habits and vehicle types, ensuring both performance and safety.
