What does 104h on a car tire mean?
2 Answers
The load index 104 on a tire represents a maximum load capacity of 900kg, and the speed rating 'h' indicates a maximum speed of 210km/h. The main functions of tires are: 1. To support the entire weight of the vehicle, bear the load of the car, and transmit forces and moments in other directions. 2. To transmit traction and braking torque, ensuring good adhesion between the wheel and the road surface to improve the car's power performance, braking performance, and passability; and to work together with the car suspension to cushion the impact during driving and dampen the resulting vibrations. 3. To prevent severe vibrations and early damage to car components, adapt to the vehicle's high-speed performance and reduce driving noise, ensuring driving safety, handling stability, comfort, and energy efficiency.
Oh, the 104H marking on the tire is actually quite straightforward. 104 represents the load index, meaning this tire can bear a maximum weight of 900 kilograms, while H is the speed rating, indicating a top speed capability of 210 kilometers per hour. I've seen many car owners overlook this, leading to excessive wear or even blowouts when overloaded, which is especially dangerous on highways. When selecting tires, it's crucial to match the original manufacturer's specifications—check the recommendations on the door jamb or in the manual. Don't compromise safety by opting for cheaper, unsuitable tires, as this can result in longer braking distances or unstable handling. Regular checks on tire pressure and tread wear are also vital for safe driving. Remember, these numbers aren't arbitrary; they directly impact your driving safety, which is why I always remind friends to choose tires according to the manual.
