What does H represent on car tires?
1 Answers
Car tire H represents the speed rating of the tire. Each tire's sidewall is molded with a speed symbol (also known as speed rating), which indicates the maximum speed capability of that tire. Tire specifications are commonly represented by a set of numbers, where the first number indicates the tire section width and the latter represents the rim diameter in inches. It denotes the maximum speed at which the tire can carry a specified load under defined conditions. Letters from A to Z represent certified speed ratings ranging from 4.8 km/h to 300 km/h. Common speed ratings include: Q: 160 km/h; R: 170 km/h; S: 180 km/h; T: 190 km/h; H: 210 km/h; V: 240 km/h; W: 270 km/h; Y: 300 km/h; Z: ZR indicates speeds above 240 km/h.
