[RonanLynn]

Generally, passenger car tire sizes commonly include 185/65/R14, 185/65/R15, and 205/55/R16. Below is a detailed introduction to tire specifications: 1. Specification model representation: Tires are important components of a car, and there are many specification models of tires, with different models suitable for different types of vehicles. The specification model identification is usually on the side of the tire, represented by a series of alphanumeric characters, corresponding to the tire's tread width, aspect ratio, type, rim size, load index, and speed rating. 2. Speed rating: Based on the maximum speed they can withstand, tire speed ratings can be divided into different grades from A to Z, with grade A further subdivided into eight different levels from A1 to A8. Generally, the further back the letter representing the tire speed rating is, the better the tire performance.
