The difference between 92V and 92H at the end of a tire?

Here are the differences between 92V and 92H at the end of a tire: 1. Difference one: different speed limits. The maximum speed for H grade is 210km/h, while for V grade it is 240km/h. 2. Difference two: different applications. H grade is generally used more for sports sedans, while V grade is generally used more for sports cars. The meanings of 92V and 92H: 92 represents the load index of the tire, which is the maximum weight the tire can bear. 92 means the tire can bear a maximum weight of 630 kilograms. H and V represent the speed rating of the tire. H means the tire can withstand a maximum speed of 210KM/H. V means the tire can withstand a maximum speed of 240KM/H.
As an experienced driver, I did thorough research on the difference between 92V and 92H when changing tires last time. Both numbers represent the load index, indicating 630 kg capacity - no issue there. The key difference lies in the letters V and H, which are speed rating codes. According to the tire manual, H means the tire can withstand up to 210 km/h, while V stands for 240 km/h. Don't underestimate this 30 km/h difference - during high-speed cornering, the friction-induced temperature difference can exceed 40°C. V-rated tires use more heat-resistant rubber compounds and reinforced sidewall structures. For performance cars, V-rated tires are recommended as rapid acceleration may cause tire deformation with lower ratings. Of course, they cost about 100 RMB more. For daily commuting, H-rated tires are perfectly adequate unless you frequently drive on highways.
After 20 years in auto repair, I often encounter car owners asking this question. The letter following 92 indicates the tire's heat resistance and speed limit, with H corresponding to 210 km/h and V to 240 km/h. Don't think you can race with H-grade tires; exceeding the temperature limit will soften them like boiled dumpling wrappers. V-grade tires incorporate aramid cords and a special carbon black formula to withstand temperatures up to 300 degrees. I've seen H-grade tires used on mountain roads with treads worn into wave patterns. It's advisable to choose the grade as per the manual; if you frequently drive on highways, it's worth upgrading to V-grade—after all, a tire blowout is no joke.
