What does 104h on a tire mean?
2 Answers
Tire 104h refers to the load index of the tire, where 104 indicates a maximum load capacity of 900kg, and h denotes a speed rating of 210km/h. The speed rating represents the maximum speed at which the tire can carry a specified load under defined conditions. When replacing tires, it is essential to understand the load index, speed rating, and specifications of the vehicle's tires. Tires are typically mounted on metal rims, supporting the vehicle body, absorbing external shocks, maintaining contact with the road, and ensuring driving performance. Tires often operate under complex and demanding conditions, enduring various deformations, loads, forces, and extreme temperatures during use. Therefore, they must possess high load-bearing capacity, traction performance, and cushioning properties.
Speaking of the 104H on tires, as a veteran driver with over 20 years of experience, I remember it clearly. The number 104 is the load index, indicating the maximum weight the tire can bear—specifically, 104 corresponds to approximately 875 kilograms. The H is the speed rating, meaning the tire is designed for a maximum speed of 210 kilometers per hour. In real-world driving, I've seen fellow drivers suffer consequences for ignoring these markings—such as overloading leading to tire deformation or rapid wear, or mismatched speed ratings causing blowouts during high-speed driving. Tires are crucial for vehicle support, so never take them lightly. I recommend choosing tires based on the vehicle manual, regularly checking tire pressure and wear, and prioritizing safety. Before heavy loading or long-distance trips, ensure the tire parameters meet standards—this extends their lifespan and improves fuel efficiency.
