What is the eccentric wear of automobile tires?

The reasons for tire eccentric wear are generally four-wheel alignment, tire level and air pressure. The problem of four-wheel alignment is generally related to four aspects: toe-in, camber, kingpin camber and kingpin caster. The problem of tire grade, although the tires are the same model, different grades of tires will lead to accelerated tire wear in high-rise buildings and buildings;

Air pressure problem: The tire air pressure is too strong, the wear of the middle crown is accelerated, or the air pressure is insufficient, the wear of the inner bow and outer crown of the tire is accelerated, and the tires with different air pressures on the left and right tires are worn.

Extended data:

Solution:

1, and the tires are rotated periodically. Maintain uniform tire wear, and do four-wheel alignment every 5000 ~ 10000 km to avoid abnormal tire wear. The tires installed on the same axle should not be of different models or have great differences between the old and the new;

2. Keep the wheels balanced regularly. If the wheel balance is not up to standard, high-frequency oscillation will occur when driving at high speed, which will lead to eccentric wear of tires, which is not conducive to driving safety;

3. Always check the tires, and do a comprehensive and detailed inspection before going to the expressway, including tire pressure, whether there are cracks on the sidewall and tread wear. If hidden dangers are found, they should be handled in time.
