What is the reason why the rear wheel of the car eats tires?

Tires with regular edges and basically the same width have serious wear on the upper and lower sides, which must be caused by insufficient tire pressure when the arch plate is excluded.

The tire wears evenly, but the amount of wear is large, without eccentric wear or wave wear. The general reason is that the road conditions are not good and the tire patterns are not suitable for special roads. Improper maintenance of users, mixed tires and untimely transposition can increase the mileage by 20%; Severe overload, resulting in tire overload; The higher the ambient temperature, the shorter the tire life. One rim of the whole vehicle tire is regularly worn, which is a typical damage of the rubber sleeve of the thrust rod. Solution: Replace the rubber sleeve and adjust the wheelbase. Rubber sleeves must be replaced periodically or according to mileage. If there are two or four tires on a bridge at the same time, the tires on both sides will be eaten regularly and evenly. Solution: Check whether the riding bolt of the spring bow plate is loose and whether the central bolt of the bow plate is broken. If there are any problems, please repair them accordingly. One or more grooves on the top of the tire are seriously worn, which is caused by the serious wear of the balance bar or the looseness of the tie rod. Solution: Repair or replace the beam pin and beam, tighten the pull rod, and remember that the beam must be oiled regularly. One or two large treads on the wheel tread are worn, and two tires appear at the same time, which is basically the reason for braking the wheel hub. Solution: Drill holes or replace rollers. Serious irregular gnawing on one or both sides of a single tire is basically caused by the deformation of the steel ring. Solution: Replace the steel ring. You can buy high-quality rims by eating less steamed bread. Don't be reluctant to part! Excessive difference between the old and new tires in the left and right corners can also cause unexplained tire eating. Solution: Replace the tires with new ones.
