175 means that the tire width 70R is the hub radius 14 is the tire layer
Tire is an important part of the car, there are more than 10 kinds of markers on the car tires, the correct identification of these markers on the tire matching, use, maintenance is very important for the protection of traffic safety and extend tire life is of great significance. Tire Specifications: Specifications are tire geometric parameters and physical properties of the logo data. Tire specifications are often used in a set of numbers, the previous number indicates the width of the tire section, and the latter number indicates the rim diameter in inches. The middle of the letter or symbol has a special meaning: "x" that high-pressure tire; "R", "Z" said radial tire; "a" that low-pressure tire. Level: level refers to the tire layer as a plastic layer of the number of layers, and the actual number of ply is not exactly the same, is an important indicator of tire strength. Level with the Chinese logo, such as 12 levels; with the English logo, such as "14P.R" that is 14 layers of pole. Cylindrical material: Some tires are individually marked, such as "nylon" (NYLON), generally marked after the level; the world's tire manufacturers marked in the specifications, with the first letter of the Chinese alphabet, such as 9: 00-20N , 7.50-20G, etc., N for nylon, G for steel, M for cotton, and R for rayon. Load and pressure: the general mark the maximum load and the corresponding pressure, the load to "kg" as a unit, the pressure that tire tire pressure, the unit is "kPa." Rim Size: Indicates the rim size that matches the tire. Easy to use.
The so-called radial tire (R) is usually said that the steel tire, anti-tires. Compared to Michelin in this regard be done the best. Low-pressure tire (-) is usually said line tire, easier to wear and be leaked. Usually the same brand of the same type of steel tire than the line of twists and turns twice.
