What is ATR tire?

The so-called ATR tire is the "all-road" tire. It provides significant power level and flexible control for drivers and vehicles, and can provide the same comfort as asphalt pavement on off-road pavement; On the highway, it can maintain a quiet state and the best driving accuracy.

In China's national tire standards, American tire rim manuals, European tire rim standards, Japanese tire standards and international tire standards, they can be classified into the following categories according to their uses:

1. Automobile tires-tires installed on automobiles, mainly used for high-speed driving on good roads. The maximum running speed can reach more than 200 km/h, which requires comfortable riding, low noise, good maneuverability and stability. Most tire structures adopt radial structure. According to the requirements of driving speed, it is divided into different series. In the standards and manuals, series 95 and 88 are bias tires, and series 80, 75, 70 and 65 are radial tires.

2. Light truck tires-generally refers to truck tires with a rim diameter of 16 inch or less and a section width of 9 inches or more. This kind of tire is mainly used on roads, and the driving speed can generally reach 80 ~100 km/h.

3. Truck and bus tires usually refer to truck, dump truck, various special and trailer tires with a rim diameter of 18 ~ 24 inches and a section width of more than 7 inches. Its driving road surface is complex, including good asphalt road, poor gravel road, dirt road, muddy road, ice and snow road, and even no road surface condition, and the driving speed generally does not exceed 80 km/h. 。

4. Construction machinery tires-Construction machinery tires are installed on special construction machinery vehicles, such as loaders, bulldozers, excavators, graders, road rollers and Stonecutters. The driving speed is not high, but the requirements for road conditions and load performance are high. The tire mainly adopts bias tire structure, but French Michelin company (Cantonese, Mandarin is Michelin) also adopts radial structure. According to the tire section width, it can be divided into two series: standard tire and wide base tire.

5. Off-road vehicle tires-Off-road vehicles are driven by front and rear wheels. Off-road tires mainly run on bad roads, such as desert, muddy land, soft soil or other unpaved roads, which require high passing performance. Off-road tires often use low air pressure, and some also use pressure regulating tires to adjust tire air pressure according to road conditions. In order to improve off-road trafficability, measures such as widening tire section and rim width and reducing rim diameter are generally adopted to increase the grounding area and reduce the grounding pressure. The tire structure adopts radial structure and bias tire structure.

6. Agricultural and forestry machinery tires-Agricultural tires are mainly used for tractors, Cumberland combine harvesters and agricultural machinery vehicles. Forestry machinery tires are installed on forestry tractors and forestry machinery to carry out forestry logging, skidding and shoveling. These two kinds of tires are characterized by low speed requirements, but harsh service conditions. They often run on poor field roads, hard stubble or rocky mountain roads, or even unpaved roads, and their tires are easily scratched or cut. Another feature is intermittent operation, short mileage, but long service life, so the tire is required to have good flex cracking resistance and aging resistance. The tire is mainly diagonal structure, but it also adopts radial structure.

7. Industrial vehicle tires-mainly used for pneumatic tires, semi-solid tires and solid tires on industrial vehicles. There are battery car tires, forklift tires and flatbed tires.

8. Motorcycle tires-tires for motorcycles. Include motorcycle tires, moped tires and motorcycle tires with small wheel diameters.

9. Aviation tires-pneumatic tires for airplanes.

10. Special vehicle tires-including artillery tires, tank tires, armored vehicle tires, desert tires, explosion-proof vehicle tires, etc.

12. Electric bicycle tires.
