What causes cars to eat tires?

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

Solution: Check and replenish the tire pressure.

2. The tire wears evenly, but the amount of wear is large, and there is no eccentric wear and wave wear. The general reason is that the road conditions are poor and the tire patterns are not suitable for special roads; Improper user maintenance, mixed tires, and no timely transposition, timely transposition of tires can increase the mileage by 20%; Severe overload, resulting in tire overload; The higher the ambient temperature, the shorter the tire life.

Solution: Replace qualified tires.

Tire toe-in value of four-wheel alignment:

The purpose of the inner splayed foot structure is to correct the outward rotation of the wheel caused by the camber angle of the front wheel. As mentioned earlier, steering wheel operation becomes easy due to camber angle.

On the other hand, because the wheels are inclined, the left and right front wheels rotate outward respectively. In order to correct this problem, if the left and right wheels have inward angles, plus or MINUS zero, the left and right wheels can keep moving in a straight line and reduce tire wear.
