What do V and W mean on tires?
1 Answers
The V and W markings on tires indicate the tire's certified speed rating, which represents the maximum permissible speed for the tire. W stands for a maximum speed of 270 km/h, V for 240 km/h, H for 210 km/h, and Y for 300 km/h. Below is a detailed explanation: 1. Tire maximum speed: The maximum speed of a tire refers to the highest speed it can safely handle. When using the tire, the driving speed must not exceed this maximum speed. Exceeding the tire's maximum speed rating can lead to inadequate heat dissipation, increasing the risk of a blowout, and the tire may not maintain normal performance at such speeds. 2. Classification of tire speed ratings: Generally, the further the letter representing the tire speed rating is in the alphabet, the better the tire's performance and the higher its price. Tires with different speed ratings are suitable for different types of vehicles. P—T rated tires (maximum speed 150—190 km/h) are suitable for small and compact cars, U—V rated tires (maximum speed 200—240 km/h) are for mid-to-high-end sedans, and the highest-performing W—Z tires, which can handle speeds between 240—300 km/h, are typically used in large luxury cars and supercars.
