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.

H and V tires often go hand in hand. While the V rating technically allows for a higher maximum speed, practically speaking, this a distinction without much of a difference in light of U.
