What does the H on car tires represent?
2 Answers
Car tire H refers to the speed rating of the tire. The speed rating indicates the speed at which the tire can carry a specified load under specified conditions. Below are the steps for replacing car tires: 1. After parking and turning off the engine, use the handbrake to stop the vehicle; 2. Place heavy objects in front of and behind the wheels to prevent sliding, and set up a triangular warning sign behind the car; 3. Use a wrench to loosen the screws of the tire to be replaced in a diagonal pattern; 4. Place the jack on the side where the tire needs to be replaced and lift the vehicle to a certain height; 5. Remove the screws and take off the tire; 6. Replace it with a spare tire or a new tire, tightening the screws in a diagonal pattern; 7. Lower the vehicle by releasing the jack and ensure that the screws and nuts are tightened properly. Extension: Tires are circular elastic rubber products installed on metal rims, used on various vehicles or machinery to support the vehicle body, cushion external impacts, achieve contact with the road surface, and ensure the vehicle's driving performance.
I remember when I was young and driving, I was very particular about the H marking on the tires. H represents the speed rating of the tire, meaning its maximum safe speed is 210 kilometers per hour. This is important because if you use the wrong tire, such as one with a speed rating that's too low, it can easily blow out at high speeds and cause an accident. When looking at those alphanumeric combinations on the side of the tire, the H usually appears after the size code, and other similar ratings like S represent 180, and V represents 240. I recommend everyone check the recommended rating in the vehicle manual before replacing tires, and not just buy any cheap one. Regular tire maintenance can extend their lifespan. Every time I wash my car, I take a moment to check the condition of the tires—safety first.
