What do 97V and 97W tires mean?

[DiAnna]

The following explains the meanings of 97V and 97W tires: 97 represents the load index of the tire, indicating that the tire can bear a weight of 730kg. W and V represent the speed ratings of the tire, with W being 270km/h and V being 240km/h. Here is additional information about W and V: 1. The further back the letter representing the tire speed rating is in the alphabet, the better the performance of the tire, and the higher the price. 2. Tires with different speed ratings have different applicable ranges. P—T rated tires are suitable for small and compact cars, U—V rated tires are suitable for mid-to-high-end cars, while the best-performing W—Z tires, which can withstand speeds between 240—300km/h, are usually used in large luxury cars and supercars. 3. From these two parameters alone, 97W is better than 97V, with a higher speed rating, indicating better heat dissipation and performance of the car tire. However, car tires are not judged solely on this; for example, the wear resistance index of car tires, where current economical tires can generally exceed 300.
