What do the letters h and v at the end of a tire represent?

[SanKimberly]

The letters h and v at the end of a tire represent the speed rating. The letter v stands for a maximum speed of 240 km/h, while h represents a maximum speed of 210 km/h. The functions of tires are: 1. Transmitting driving force, braking force, and steering force to enable vehicle operation; 2. Supporting the vehicle load; 3. Reducing and absorbing vibrations and impact forces during driving to prevent severe vibrations from damaging vehicle components. Methods for maintaining car tires: 1. Regularly check tire pressure; 2. Remove debris from tire treads; 3. Inspect tire wear and replace them promptly based on wear conditions; 4. Perform tire rotation to ensure even wear distribution among all four tires and prevent excessive wear.
