What Does the Tire Model Number Mean?

[KeiraAnn]

Tire model numbers represent the tire's width, aspect ratio, type, and applicable size. For example, a tire model number like 205/60R16 can be interpreted as follows: The first number 205 indicates the tire width is 205 millimeters. The number 60 denotes the tire's aspect ratio is 60%, meaning the sidewall height is 60% of the tire's width. The letter R stands for radial tire, and 16 signifies the rim diameter is 16 inches. In addition to the model number, tires also display the following common specifications: Carcass ply material: Indicated by Chinese pinyin abbreviations, such as M for cotton cord, R for rayon cord, N for nylon cord, G for steel cord, and ZG for steel radial cord. Speed rating: Indicates 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; H: 210 km/h; V: 240 km/h; W: 270 km/h; Y: 300 km/h. Rim specification: Shows the compatible rim size for the tire, facilitating practical use, such as "Standard Rim 5.00F".
