What do the letters representing speed on car tires mean?
1 Answers
Car tire speed ratings are represented by letters, indicating the maximum speed at which the tire can carry a specified load under defined conditions. Different letters correspond to different speed ratings. For example: W represents a maximum speed of 270 km/h, V represents 240 km/h, and H represents 210 km/h. More tire letters can be referenced against the tire speed rating table. Below is an introduction to tires: 1. Introduction: Tires are circular elastic rubber products mounted on various vehicles or machinery for rolling contact with the ground. 2. Performance: Tires are often used under complex and demanding conditions, enduring various deformations, loads, forces, and high/low temperatures during operation. Therefore, they must possess high load-bearing capacity, traction performance, and cushioning performance. 3. Markings: Tires are crucial components of automobiles, with over 10 types of markings on car tires. Correctly identifying these markings is essential for tire selection, usage, and maintenance, playing a significant role in ensuring driving safety and extending tire lifespan.
