What do the letters V and H on the back of the tires stand for?

Car owners may find that there are different letters marked on the car tires and do not know what these letters stand for. So do you know what the letters V and H on the back of the tire stand for?

The letters V and H behind the tires each represent the speed level, where V represents the maximum driving speed of 240km/h, and H represents the maximum driving speed of 210km/h.

You must know that the faster the vehicle speed, the greater the friction between the vehicle's tires and the ground, which will generate huge amounts of heat. Therefore, cars driving at high speeds require tires with high temperature resistance. The higher it is, tire V has better high temperature resistance than tire H. In terms of price, the price of tire V is also higher than that of tire H.

There are many grades of tires, arranged from A to Z according to certified speed grades. The selection of vehicle tires will be determined according to the size and model of the car. Usually, small vehicles use P-T type tires, while mid- to high-end cars use U-V type tires. As for large luxury cars or sports cars, they use W-Z type tires with better performance.
