Among them, "H" means that the top speed of the tire is 210 kilometers per hour, while "V" means that the top speed of the tire is 240 kilometers per hour. These speed grades are tested and certified in accordance with international standards during tire manufacturing, and car owners need to choose the appropriate speed grade according to their own driving needs and driving habits when choosing tires.

The speed grade of the tire is directly related to driving safety. If the speed grade of the tire does not meet the maximum speed, then the tire may have excessive wear, flat tire and other dangerous conditions at high speed, and the consequences are unimaginable. Therefore, when choosing tires, car owners must pay attention to the choice of speed grades to ensure that the speed grades of tires can meet their driving needs.

Together with the speed grade, these performance indicators determine the overall performance of the tire. When choosing tires, car owners not only pay attention to the speed grade, but also need to comprehensively consider other performance indicators of tires, and choose the tires that are most suitable for their cars and driving habits.
