Automobile tire model numbers refer to the meanings of various symbols on the tire. This includes the tire specifications, ply rating, rim specifications, speed rating, etc. Specific explanations are as follows: 1. Tire specifications: Usually represented by a set of numbers, where the first number indicates the tire section width and the latter represents the rim diameter, measured in inches. 2. Ply rating: The ply rating refers to the nominal number of cord layers in the tire rubber, which may not exactly match the actual number of cord layers, serving as an important indicator of tire strength. 3. Rim specifications: Indicates the rim specifications compatible with the tire for practical use. 4. Speed rating: 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 4.8km/h to 300km/h. Common speed ratings: Q: 160km/h; R: 170km/h; S: 180km/h; T: 190km/h; H: 210km/h; V: 240km/h; W: 270km/h; Y: 300km/h; Z: ZR speed exceeds 240km/h.
