What Does the Tire Specification Represent?

[June]

Tire model numbers indicate the type of tire, tire size, the maximum speed the tire can withstand, the production year of the tire, and more. For example, 235/55-R17 99V represents, from left to right, the width of the tire, the thickness of the sidewall, the diameter of the corresponding rim, and the maximum speed the tire can withstand. Specific details are as follows: 1. Tire Numbering: International standard tire numbering uses millimeters to indicate the section width and the percentage of the aspect ratio. 235 means the tire width is 235mm, 55 indicates the aspect ratio of the tire section is 55%, meaning the section height is 55% of the width. 17 represents the diameter of the rim the tire corresponds to, 99 stands for the load index of the tire, and V indicates the speed rating of the tire. 2. Tire Model: The tire model represents various information about the car tire. Tire model specifications are often represented by a set of numbers, such as 165/70R14, which indicates a radial tire with a width of 165 millimeters, an aspect ratio of 70, and a rim diameter of 14 inches. 165 denotes the section width of the tire, 70 means the aspect ratio of the tire section is 70%. The aspect ratio is the ratio between the section height and the section width of the tire, and the rim diameter is 14 inches.
