What does 84h tire mean?
3 Answers
84h tire refers to the load index and speed rating of the tire, where 84 indicates the load index, meaning the tire can bear a weight of 500 kilograms; h indicates the speed rating, meaning the tire can handle speeds up to 210 kilometers per hour. The functions of a tire are: 1. To bear the weight of the vehicle; 2. To ensure good adhesion between the wheel and the road surface; 3. To improve the vehicle's traction, braking, and off-road capability; 4. To directly contact the road surface and work with the vehicle's suspension to cushion the impact during driving, ensuring good ride comfort and smooth driving. The maintenance methods for tires include: 1. Regularly removing debris from the tread grooves; 2. Checking the tire wear and replacing them in time; 3. Regularly checking the tire pressure; 4. Promptly repairing punctures.
I remember once going on a long trip with friends, the car was loaded with a lot of luggage, and after returning, I noticed abnormal tire wear. Upon closer inspection, I saw the 84H marking. The 84 indicates that each tire can bear approximately 500 kilograms, and the H means the maximum safe speed is 210 kilometers per hour. That experience taught me that overloading or driving too fast can make the tires unable to handle the stress, leading to safety hazards. When choosing tires, it's essential to match them with the vehicle's weight and driving habits, not just go for the cheapest option. For SUVs or vehicles that frequently carry heavy loads, ensuring the load index is sufficient is crucial. Tire maintenance is also key—regularly checking tire pressure and tread can prevent many issues. Behind this small marking lies great wisdom, directly related to our driving safety.
When I first learned to drive, I knew nothing about tires. My instructor explained the meaning of 84H tires: 84 is the load index, approximately 500 kg per tire, and H is the speed rating, meaning it can safely reach a maximum speed of 210 km/h. This marking is usually found on the sidewall of the tire, and when selecting tires, it should match the vehicle manual. Don’t overlook this, as it could lead to blowouts or unstable handling. I recommend checking what markings your car requires before each tire change, especially for vehicles that frequently drive on highways or carry heavy loads. Simply put, 84 indicates the load capacity, and H is the speed limit—remembering these will make driving safer. Also, pay attention to tire pressure regularly, keeping it moderate to extend tire life.
