What does 108H mean for car tires?
1 Answers
Tire 108H refers to the load index of the tire, where H indicates a speed rating of 210 km/h. The speed rating denotes the maximum speed at which the tire can carry a specified load under defined conditions. The number 108 represents a load index of 1000 kg, which is the maximum load a single tire can bear, expressed as a code in kilograms. When replacing tires, it's essential to understand the load index, speed rating, and specifications of the car tires. Tires are typically mounted on metal rims, supporting the vehicle body, absorbing external shocks, ensuring contact with the road, and maintaining driving performance. Tires often operate under complex and demanding conditions, enduring various deformations, loads, forces, and temperature extremes during use. Therefore, they must possess high load-bearing capacity, traction, and shock absorption properties. When selecting a tire's load index, it's necessary to calculate based on 1.5 times the vehicle's total weight. For example, a load index of 100 corresponds to 800 kg. A typical passenger car has four tires, multiplying by four gives 3200 kg. Calculating at 1.5 times, four tires with a load index of 100 can support a vehicle weighing up to 2133 kg. The speed rating should be chosen based on actual conditions and the vehicle's performance parameters, and this index is independent of the number of tires.
