What does wheel speed rating mean?
1 Answers
Wheel speed rating refers to the maximum speed at which a wheel can carry a specified load under defined conditions. The speed rating is denoted by English letters, representing the tire's maximum permissible speed capability. These letters follow the sequence of the 26-letter English alphabet, with later letters indicating higher maximum speed limits. The speed ratings corresponding to each letter are as follows: 1. Q: 160 km/h; 2. R: 170 km/h; 3. S: 180 km/h; 4. T: 190 km/h; 5. H: 210 km/h; 6. V: 240 km/h; 7. W: 270 km/h.
