  • What Is a 'W' Speed Rating for Tires? - Reference.com

    2020-3-25 · A W speed rating on a tire indicates that the manufacturer produced the tire for use on exotic sports cars. The W rating gives the tire a maximum speed capacity of 168 miles per hour. A tire's speed rating identifies the highest speed a vehicle should reach. A Y rating, for example, means that the tire can handle speeds up to 186 miles per hour.

    H speed ratings are common in the grand touring all-season tire category. W. A W means the tire is approved for speeds up to 168 mph (270 km/h) under optimal conditions. W speed rated tires land firmly at the performance end of the speed rating spectrum. Ws are suitable for performance coupes and sedans, and even street driven exotic sports cars.
