What speed does the H on a tire represent?
2 Answers
Tire H represents a maximum speed of 210 kilometers per hour. Below is a detailed introduction to car tire specifications: 1. Specification model representation: Tires are important components of a car, and there are many specification models for tires. Different specification models are suitable for different types of vehicles. The specification model identification is usually on the side of the tire, represented by a series of alphanumeric characters, corresponding to the tire's tread width, aspect ratio, type, rim size, load index, and speed rating. 2. Speed rating: According to the different maximum speeds they can withstand, tire speed ratings can be divided into different grades from A to Z, with grade A further subdivided into eight different grades from A1 to A8. The further back the letter representing the tire speed rating is, the better the tire performance.
The H code on tires represents a maximum speed of 210 km/h. As someone who frequently drives on highways, I pay special attention to this when replacing tires. My car originally came with H-rated tires, but I once switched to cheaper T-rated ones (190 km/h). During a high-speed overtake, I felt the tires were unstable and immediately slowed down to check. Choosing tires that match your vehicle's top speed and driving habits is crucial—sports cars may require V-rated (240 km/h) or higher. Never risk using lower-rated tires, as speeding can cause overheating and blowouts, which is extremely dangerous. Safety first—regular maintenance and tire condition checks are highly recommended.
