Tires are important parts of automobiles. There are more than 10 types of marks on automobile tires. Correctly identifying these marks is important for the selection, use and maintenance of tires, and is of great significance for driving and prolonging the service life of tires.
Tire size: The size is the symbol data of the geometric parameters and physical properties of the tire. Tyre specifications are often represented by a set of numbers. The first number represents the width of the tire section, and the latter number represents the diameter of the rim, all in inches. The letters or symbols in the middle have meanings: "x" means high-pressure tires; "R" and "Z" mean radial tires; "一" means low-pressure tires.
Layer level: Tier level refers to the nominal number of plies in the rubber layer of the tire, which is inconsistent with the actual number of plies. It is an important indicator of tire strength. The level is marked in Chinese, such as level 12; and the level is marked in English, such as "14P.R", which is the 14th level.
Cord material: Some tires are individually marked, such as "nylon" (NYLON), which is generally marked after the level; some tire manufacturers in the world mark the specifications after the specifications, which are represented by a letter in Chinese pinyin, such as 9:00-20N, 7.50 —20G, etc., N stands for nylon, G stands for steel wire, M stands for cotton thread, and R stands for rayon.
Load and air pressure: general sign. Large load and corresponding air pressure. The load is in kilograms, and air pressure is the tire pressure in kilopascals.
Rim specification: indicates the rim specification used to match the tire. It is convenient for practical use. Such as "standard rim 5.00F".
Balance mark: It is made of colored rubber and is vulcanized on the sidewall to indicate that the tire is light. When assembling, it should face the valve to ensure the balance of the entire tire.
Rolling direction: The pattern on the tire is particularly critical for drainage during driving. Therefore, off-road vehicle tires with asymmetrical patterns often use arrow signs to assemble the rolling direction to design adhesion and other performance. If it is installed incorrectly, it will be counterproductive.
