Although both "V" and "H" on tires represent speed ratings, their main difference lies in the maximum speed they can handle. Despite the difference of just one letter, the speed variance is significant. "V" indicates a maximum speed of 240 km/h, while "H" signifies a maximum speed of 210 km/h.
Tires are crucial safety components of a vehicle, so when replacing them, it's essential to choose based on the car's speed standards. Besides "V" and "H," there are other letters representing tire speed ratings.
1：Speed Rating "P": Maximum speed of 150 km/h;
2：Speed Rating "Q": Maximum speed of 160 km/h;
3：Speed Rating "R": Maximum speed of 170 km/h;
