According to the purpose of the tire
For example, in China's tire national standards, the US tire rim manual, the European tire rim standard, the Japanese tire standard and the international tire standard are classified by use, and can be divided into the following types:
1. Car tires - is a tire mounted on a car, it is mainly used for high-speed exercise on a good road surface, the maximum speed can reach more than 200 km / h, requires comfortable ride, low noise, good maneuverability and stability Sex. Most of the tire structures use a meridian structure. According to the requirements of driving speed, it is divided into different series. Among the standards and manuals, 95 and 88 series are bias tires, and 80, 75, 70 and 65 series are radial tires.
2. Light-duty truck tires – usually truck tires with a rim diameter of 16 inches or less and a section width of 9 inches or more. These tires are mainly used on highways, and the driving speed is generally 80-100km/h.
3. Truck and bus tires usually refer to trucks with a rim diameter of 18 to 24 inches, a section width of 7 inches or more, and self-unloading trucks, various special and trailer tires. The driving road is more complicated, there are good asphalt roads, poor gravel roads, dirt roads, mud roads, ice and snow roads, and even no road conditions. The driving speed is generally not more than 80km/h. 4. Construction machinery tires— - Construction machinery tires are installed on construction machinery vehicles for special operations, such as loaders, bulldozers, excavators, leveling land machines, road rollers and stone working machines. The driving speed is not high, but the road conditions and load performance used are demanding. The tires mainly adopt the bias tire structure, but the French Miqi wheel (Yueyin, Mandarin called Michelin) also adopts the meridian structure. From the tire section width classification can be divided into two series of standard tires and wide base tires.
5. Off-road car tires - off-road vehicles are driven by front and rear wheels. Off-road vehicle tires mainly travel on bad roads such as desert, muddy ground, soft soil or other roadless roads, requiring high pass performance of tires. Off-road tires tend to use low air pressure, and some also use pressure-regulated tires, depending on road conditions. To adjust the size of the tire pressure. In order to improve off-road passage, measures such as widening the tire section and rim width, and reducing the rim diameter are generally used to increase the grounding area and reduce the grounding pressure. In addition to the biased tire structure, the tire structure also uses a meridian structure.
