What does 102Y tire mean?

[ClaireMarie]

102 indicates a load index of 850kg, and Y means the maximum speed of this tire is 300 km/h. Some tires also have speed limit symbols marked with letters such as P, R, S, T, H, V, Z representing various speed limits. The following are the functions of car tires: 1. Support the full weight of the vehicle: Car tires support the full weight of the vehicle, bear the load of the car, and transmit forces and moments in other directions. 2. Improve vehicle performance: Car tires transmit traction and braking torque to ensure good adhesion between the wheels and the road surface, thereby improving the car's power performance, braking performance, and off-road capability; they work together with the car suspension to cushion the impact during driving and dampen the resulting vibrations. 3. Prevent early damage to car components: Car tires prevent car components from suffering severe vibrations and early damage, adapt to the high-speed performance of the vehicle, reduce driving noise, and ensure driving safety, handling stability, comfort, and fuel economy.
