The meaning of the data on car tires:

1. Tire specifications: Specifications are symbolic data of tire geometric parameters and physical properties. There are three ways to express tire specifications: A. Metric (m); B. Mixed metric and imperial; C. Imperial; Imperial tire specifications are often represented by a set of numbers. The first number represents the tire cross-section width, and the latter number represents the rim diameter, both in The unit is inches. The letters or symbols in the middle have special meanings:

2. Tire structure: "R" represents radial tires, "D" and "一" represent bias tires.

Others: "XL" means partially reinforced tires, "TG" means engineering tractor and grade machine tires (off-road use), "NHS" means off-highway tires.

3. Layer: Layer refers to the nominal number of layers of cords in the rubber layer of the tire, which is not completely consistent with the actual number of cords. It is an important indicator of tire strength. Levels are marked in Chinese, such as level 12; levels are marked in English, such as "14P.R" which means level 14.

4. Cord material: Some tires are marked separately, such as "nylon" (NYLON), which is usually marked after the layer; some tire manufacturers mark it after the specifications, using the first Chinese pinyin Letter representation, such as 9.00-20N, 7.50-20G, etc., N represents nylon, G represents steel wire, M represents cotton thread, and R represents rayon.

5. Load and air pressure: Generally, the maximum load and corresponding air pressure are marked. The load is in "kg" and the air pressure is the tire pressure in "kilopascals".

6. Rim specifications: Indicates the rim specifications that match the tires. Convenient for practical use, such as "Standard Rim 5.00F".

7. Balance mark: The mark is made of colored rubber and printed on the sidewall, indicating that the tire is the lightest here. When assembled, it should be facing the valve to ensure the balance of the entire tire.

8. Rolling direction: The pattern on the tire is particularly critical for water drainage and anti-skid during driving. Therefore, off-road vehicle tires with asymmetric patterns are often equipped with arrows to mark the rolling direction to ensure the adhesion, anti-skid and other properties of the design. . If installed incorrectly, it will be counterproductive.

9. Wear limit mark: Rubber strips and blocks are used on one side of the tire to mark the wear limit of the tire. Once the tire wear reaches this mark, it should be replaced in time, otherwise the tire will burst midway due to insufficient strength.

10. Production batch number: Use a set of numbers and letters to indicate the year, month and quantity of the tire. For example, "98N08B5820" means the 5820th tire produced by Group B in August 1998. The production batch number is used to identify the tire's condition and storage time.

11. Other marks: such as product grade, production license number and other ancillary marks. It can be used as reference and information when choosing.
