What are the dimensions of car tires?
1 Answers
Most car tire model markings are like 175/70R1477H, where 175 represents the tire width of 175mm, 70 indicates the aspect ratio of the tire section is 70%, R stands for radial tire, the tire diameter is 14 inches, the load index is 77, and the permissible speed rating is H. The international standard car tire code expresses the section width and aspect ratio percentage in millimeters. This is followed by the tire type code, rim diameter (in inches), and load index (permissible load mass code). Tire dimensions are printed on the sidewall, with two representation methods, such as 34*7 or 7.50-20. The former indicates high-pressure tires, while the latter denotes low-pressure tires. Additionally, many other markings are printed on the sidewall, for example, D is used for light vehicles, F for medium vehicles, G for standard vehicles, and H, L, J for large luxury and high-performance vehicles.
