1, the hub edge is scratched and damaged. This situation is more common. It is easy to scratch the edge when turning against the curb while driving. In this case, just repair it with a repair stick.
2. Edge clearance of the hub. When the wheel hub is hit by a stone or a hard object, the edge of the wheel hub will be hit with a gap. At this time, it is necessary to use a special hub to fill the gap, because it has strong adhesion and is not easy to peel off after repair.
3. The wheel hub is distorted. When the automobile hub is hit or collided, it is easy to cause the rim of the automobile hub to bend and deform, which is a serious damage. As long as the internal structure of the hub is not damaged, it can be corrected by plastic repair and special straightening machine (if the deformation is too severe, it is recommended to replace the hub directly).
Several manifestations of hub deformation are as follows.
1, steering wheel jitter; If the steering wheel shakes at high speed, it is likely that the hub is deformed. At this time, it is necessary to go to the tire shop to do dynamic balance and judge whether the hub is deformed.
2. The tire leaks; If the tire leaks and there is no damage, and the inflation nozzle leaks, it must be that the hub is deformed. If the hub is deformed, it cannot be closely combined with the toe, resulting in air leakage.
3, tire curling; If the edge is outside, it is easy to be found. If it's hard to find inside, refer to the first two items.
4. The wheel hub is cracked; This situation is more serious. Usually, after a violent collision, the hub cracks and the tire will be damaged first.
