What is the difference between H and V on tires?

[Frank]

The difference between H and V on tires is the maximum speed under load conditions: H-rated tires have a maximum speed of 210 kilometers per hour, while V-rated tires can reach up to 240 kilometers per hour. When tires roll at high speeds, they generate heat due to compression and deformation. Therefore, higher-grade tires possess superior resistance capabilities. To achieve this effect, reinforcements are made on the tire shoulders and tread patterns, reducing the likelihood of tire deformation. Car tires are one of the essential components of a vehicle, directly contacting the road surface and working together with the car suspension to mitigate impacts during driving, ensuring good ride comfort and smooth driving performance.
