The unit of tires is 'set/piece'. Below is a detailed introduction to the specifications of car tires: 1. Specification model representation: Tires are important components of a car, and there are many specification models of tires, with different specification 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: According to the different maximum speeds they can bear, the speed ratings of tires can be divided into different grades from A to Z, with grade A further subdivided into eight different grades from A1 to A8. Generally speaking, the later the letter representing the tire's speed rating, the better the tire's performance.
