1、 What are the types of car tires?
1. According to the structure, it can be divided into radial tire and diagonal tire.
2. According to the pattern, it can be divided into strip pattern, horizontal pattern tire, mixed pattern tire and off-road pattern tire.
3. According to different types of vehicles, there are eight types: PC car tire, LT light truck tire, TB truck and bus tire, AG agricultural vehicle tire, OTR engineering vehicle tire, ID industrial vehicle tire, AC aircraft tire and MC motorcycle tire.
4. It can be divided into full size spare tire and non-full size spare tire.
Full size spare tire: the specification and size of the full size spare tire are identical with the other four tires of the original vehicle, and any temporary or

Tires that are no longer in use.
Non-full size spare tire: The diameter and width of the spare tire are slightly smaller than those of the other four tires, so it can only be used as a temporary substitute and can only be used for non-driving wheels. * * The speed shall not exceed/h.
5. It can be divided into zero pressure tires.
Zero pressure tire: Zero pressure tire is also called run flat tire, that is, it is usually called explosion-proof tire. Compared with ordinary tires, zero pressure tires do not leak or are very slow, and can maintain the driving profile. The tire rims can be fixed on the rims all the time to ensure that the car can be driven stably for a long time or temporarily

Repair the station.
2、 Factors Affecting Tire Life
1. Tire selection and installation: The correctness of tire installation is directly related to the service life of tires, especially when replacing new tires. As the actual size and load capacity of different tires are different, they shall not be mixed randomly.
2. Working pressure: too low or too high tire pressure will affect the service life of the tire.
3. Tire load: The greater the vehicle load, the shorter the tire life, which is beyond doubt.
4. Driving speed: tires produced by regular tire manufacturers are marked with speed level index. Tires shall be used within * * driving speed corresponding to the specified speed level index.
5. Tire temperature: The tire rises due to stretching, compression and friction during vehicle driving. Excessive temperature is easy to aggravate tire wear and even tire blowout.
6. Chassis status: parallelism of front and rear axles, four-wheel alignment, working status of braking device and technical status of other chassis components will affect vehicle wheels to varying degrees

The service life of the tire.
7. Road conditions: If the vehicle runs on the gravel road or under bad road conditions for a long time, the service life of the tire will definitely be shortened.
8. Driving habits: excessive starting, sudden steering, emergency braking, high-speed driving in areas with poor road conditions, frequent getting on and off the road teeth and tires scratching obstacles when parking will cause serious tire wear, thus reducing the service life of tires.
9. Tire maintenance: The important factors to prolong the service life of tires are timely tire transposition, selection of appropriate tread patterns, daily and frequent maintenance, regular inspection of tire pressure, timely repair, and frequent excavation of stones and foreign matters in tread patterns.
10. Vehicle maintenance: regularly check and maintain the four-wheel alignment, knuckle, wheel bearing and suspension system.
