When repairing a car with some gaps in the iron ring, find an iron plate and look at the gap between the iron plate and the wheel ring near the rotating wheel ring to see the full deformation degree of the car and correct it.

If the rim leans to the left, tighten the right steel wire and loosen the left steel wire. The right side is the opposite. But every time it is tight or loose, it can only reach half a lap or a quarter lap, and it will be OK after several times.
