What does it mean when winter tires exceed 50 kilometers?

[LaWyatt]

Winter tires exceeding 50 kilometers refers to the speed of the tires surpassing 50 kilometers. The functions of tires are as follows: 1. Driving vehicle operation: Tires serve as the medium for transmitting forces between the vehicle and the road surface, transmitting driving force, braking force, steering force, etc., thereby enabling operations such as driving, braking, and steering of the vehicle. 2. Supporting vehicle load: The load of the vehicle causes the tires to sink until the average pressure of the tire contact area balances with the inflation pressure inside the tire. 3. Reducing and absorbing vehicle vibrations and impacts: This prevents early damage to vehicle components caused by severe vibrations. At the same time, it adapts to the high-speed driving state of the vehicle and reduces driving noise, ensuring driving safety, comfort, handling stability, and fuel economy.
