How to Read Tire Model Numbers?
1 Answers
Vehicle tire model identification is as follows: 1. Most tire model markings are in the format: 205/55R16. The meanings of these numbers are: 205 represents the tire section width in millimeters (mm), generally ranging between 145-285mm with 10mm intervals; 55 is the aspect ratio, which is the ratio of the tire sidewall height to the tire section width, R indicates the tire has a radial structure, and 16 is the rim diameter in inches. 2. Some tires also contain letters or symbols with special meanings: "X" denotes a high-pressure tire; "C" indicates a reinforced type; "B" represents a bias-ply tire; "-" signifies a low-pressure tire. M and S are abbreviations for Mud and Snow respectively, indicating that the tire is suitable for use on snowy, icy, and muddy roads.
