What does H mean on tires?
2 Answers
Tire H represents the speed rating of the tire, with H indicating a maximum speed of 210 kilometers per hour. Here are some other letter ratings: 1. V has a maximum speed of 240 kilometers per hour. 2. W has a maximum speed of 270 kilometers per hour. Additional information: 1. Tires are typically mounted on metal rims, supporting the vehicle body, absorbing external shocks, ensuring contact with the road, and maintaining driving performance. 2. Tires often operate under complex and demanding conditions, enduring various deformations, loads, forces, and extreme temperatures during use. Therefore, they must possess high load-bearing capacity, traction performance, and shock absorption capabilities.
The 'H' on a tire is a speed rating symbol, indicating its maximum speed capability of 210 km/h or 130 mph. This letter is printed on the tire sidewall and commonly found in the specifications of regular passenger car tires. For instance, when I frequently help friends inspect their vehicles, I always notice this marking. It's just one part of the tire's series of parameters, with others like the load index being equally important. If your car is mainly for urban commuting, an H rating is perfectly adequate. However, for long-distance highway driving, exceeding this speed could increase the risk of a blowout. It's advisable to check if replacement tires meet the manufacturer's recommended rating and to regularly inspect tire pressure and tread wear to ensure safety.
