How to Read Tire Model and Maximum Speed?

[DiMargaret]

Tire model and maximum speed can be found on the sidewall of the tire. Here are the specific details: 1. Tire Model: There is a series of alphanumeric characters on the sidewall, such as 205/55/R16-91H, which represent the tire's specifications, i.e., the tire model. These correspond to the tire's tread width, aspect ratio, type, rim size, and load index. The last letter, H, indicates the tire's speed rating. 2. Maximum Speed: Tires with different speed ratings have different applicable ranges. P-T rated tires (maximum speed 150-190km/h) are suitable for small and compact cars, U-V rated tires (maximum speed 200-240km/h) are suitable for mid-to-high-end cars, while W-Z rated tires (maximum speed 240-300km/h) offer better performance and are therefore more commonly used in large luxury cars and supercars.
