What does 88H on a car tire represent?
3 Answers
88H on a car tire indicates that the maximum load capacity of this tire is 560kg. Below are three classifications of car tires: 1. Light truck tires: Typically refer to tires with a rim diameter of 16 inches or less and a section width of 9 inches or more, mainly used on highways with speeds generally ranging from 80 to 100 km/h. 2. Truck and bus tires: Usually refer to tires with a rim diameter of 18 to 24 inches and a section width of 7 inches or more, used on trucks, dump trucks, various specialized vehicles, and trailers. These tires operate on more complex road surfaces, including good asphalt roads, poor gravel roads, dirt roads, muddy roads, icy roads, and even roadless conditions, with speeds generally not exceeding 80 km/h. 3. Construction machinery tires: These are mounted on specialized construction vehicles such as loaders, bulldozers, excavators, land levelers, road rollers, and rock drilling machines. Although their speeds are not high, the road conditions and load performance requirements are demanding, and these tires mainly use a bias-ply structure.
I've always been curious about the 88H code on tires. As a car enthusiast, I've done quite a bit of research. The number 88 is the load index, corresponding to a maximum weight capacity of 560 kilograms per tire; the letter H is the speed rating symbol, indicating a maximum safe speed of 210 kilometers per hour. This combination is determined during tire design and must match the vehicle specifications to function properly. If the load capacity is exceeded or the speed limit is surpassed, the tire is prone to blowouts or rapid wear. I've also noticed that many car owners overlook this, such as choosing the wrong rating when replacing tires, leading to unsafe driving conditions. It's essential to check these parameters before long-distance trips. Remember, tire markings include more than just these—details like the production date also affect performance.
As a driver with twenty years of experience, I've seen plenty of 88H tire markings. The 88 refers to the load capacity—560 kilograms per tire—and the H indicates a speed rating of 210 km/h. Simply put, tires must match your vehicle's actual load and driving habits; mismatches can lead to accidents. I once witnessed a neighbor's car overloaded with incorrect tires, and the tires split open not long after—how dangerous! My advice is to glance at these markings during every car service or have a technician verify the symbols when buying new tires. Also, remember that tread depth and tire pressure are equally crucial for safety—don't focus solely on one marking.
