What is the difference between V and H rated tires?

[DiPaisley]

The difference between V and H rated tires mainly lies in their maximum speed under load conditions, with V rated tires having a higher speed capability than H rated tires. The differences between V and H rated tires are as follows: 1. Durability: When tires roll at high speeds, they generate heat due to compression and deformation. Therefore, the higher-grade V rated tires have superior durability. To achieve this, enhancements are made to the tire shoulders and tread patterns, reducing the likelihood of deformation and improving wet traction performance. 2. Speed: Under load conditions, the maximum speed for V rated tires is 240 km/h, while for H rated tires it is 210 km/h. 3. Considerations when replacing tires: Replacing original V rated tires with H rated tires has no impact, as V and H ratings represent the tire's speed category, meaning the driving speed should not exceed the maximum speed. However, it is important to note that when selecting replacement tires, they should be of the same specification, structure, manufacturer, and tread pattern as the original tires to ensure consistency.
