What is the difference between V and H on tires?

[Cara]

The difference between V and H on tires lies in their speed ratings: tires with a V rating have a maximum safe speed limit of 240 km/h, while tires with an H rating have a maximum safe speed limit of 210 km/h. The principle for replacing tires is that tires on the same axle must be of the same brand, tread pattern, size, load index, speed rating, and have similar tread depths. Tires are circular elastic rubber products mounted on various vehicles or machinery, typically installed on metal rims. They support the vehicle body, absorb external shocks, ensure contact with the road surface, and maintain driving performance. Tires are often used under complex and demanding conditions, so they must possess high load-bearing capacity, traction performance, and shock absorption capabilities.
