What does 102h on a tire mean?

Tire 102h means the maximum load capacity of the tire is 850kg and the maximum speed is 210km/h. Extended information about the tire load index and speed rating: Load Index: The vehicle load must not exceed the maximum load capacity of the tire. The load index and maximum load capacity of each tire are molded on the sidewall. For example: In the tire specification 195/65R15 106V, the load index is 106, which corresponds to a maximum load capacity of 950kg. Overloaded tires will accumulate excessive heat and may lead to sudden failure. Therefore, it is necessary to follow the load requirements of the vehicle manufacturer to ensure the tires are not overloaded. Speed Rating: The driving speed must not exceed the maximum speed of the tire. The speed rating of each tire is molded on the sidewall. By referring to the speed rating, you can determine the maximum speed of the tire. For example: In the tire specification 195/65R15 106V, the speed symbol is V. By checking the speed symbol and speed correspondence table, you can find that the maximum speed of this tire is 240km/h.
The numbers 102 and H in "102H" are two critical figures. 102 is the load index, indicating that this tire can bear a maximum weight of 850 kilograms. If you overload the vehicle, the tire may deform or burst, compromising safety. H is the speed rating, denoting a maximum speed of 210 kilometers per hour. Driving too fast may cause overheating. With years of driving experience, I always emphasize the importance of matching the original factory specifications—different vehicle weights require different indices. For example, a small car might be suitable for 102, but a large SUV may need a higher index. For daily use, always check the markings on the tire sidewall, and don’t neglect maintenance. Regularly replacing tires or checking for wear can save fuel and prevent accidents. Safe driving starts with the details—don’t choose an unsuitable model just to save money.
From a safety perspective, the '102' in 102h represents a maximum load capacity of 850kg, while 'h' indicates a speed limit of 210km/h. Overloading or speeding will significantly reduce tire lifespan and traction, especially doubling the danger during rain or snow. I've seen many cases where owners casually replaced tires without paying attention to this index, resulting in loss of control during turns. Ensuring tires match the vehicle model is crucial: check the manufacturer's manual or consult professionals. Insufficient load capacity may make the vehicle unstable and affect braking distance. Develop a habit of regular inspections to prevent blowout risks. Safety is no trivial matter—details determine safe driving.
