What does 104h on a tire mean?
2 Answers
The 104 in tire 104h is the load index of the tire, and h is the speed rating of the tire. 104 represents a maximum load capacity of 900kg, while h indicates that the tire can withstand a maximum speed of 210 kilometers per hour. The speed rating indicates the maximum speed at which the tire can carry a specified load under defined conditions. Automotive tires are one of the key components of a vehicle, directly contacting the road surface. Together with the vehicle suspension, they help cushion the impact experienced during driving, ensuring good ride comfort and smooth driving performance. They also maintain excellent adhesion between the wheels and the road surface, thereby improving the vehicle's traction, braking, and off-road capabilities.
Once when I was changing tires, I noticed a string of codes on the sidewall, with '104h' standing out prominently. The '104' is the load index, meaning each tire can bear a maximum weight of around 900 kilograms, while 'h' is the speed rating, indicating the tire can safely support speeds up to 210 km/h. If you ignore these parameters and choose tires that don't match, such as overloading or driving too fast, it can easily lead to blowouts or loss of control. That time, my friend's car wore out much faster because of the wrong tire choice. It's advisable to always check the manual when selecting tires to ensure they match the vehicle's specifications for safety. Additionally, different combinations of numbers and letters have different meanings, like '104t' or '105v', with varying load capacities and speed limits. Regular checks during daily driving can help prevent accidents.
