It can be repaired, but it is said that it will affect the strength of the hub. Iron is a kind of soft material, which is easy to lose its roundness when it is hit hard. But because iron is soft, it is easier to repair the iron hub after it is not round. Generally, the deformation repair of iron wheel hub is hammered with a sledgehammer and then put on a balancing machine for adjustment. This repair method is not only time-consuming and laborious, but also difficult to repair. Therefore, with the gradual replacement of iron hub by aluminum alloy hub, the technology of repairing iron hub out of round has become unsuccessful.

Aluminum alloy material is not only lighter than iron, but also harder than iron, which is suitable for making wheels. However, aluminum alloy is metal after all. High school physics knowledge tells us that metal is malleable, so aluminum alloy wheels will also be out of round. In addition, the hardness of aluminum alloy is high and it is difficult to repair it by hammering, so it can only be repaired by turning. Rotating the hub will make the hub thinner, unable to bear strong impact force, and easy to break when encountering potholes, which has potential safety hazards.

There are mature technologies abroad to repair the out-of-round aluminum alloy tires. They put the hub back into the mold by heating, but at present, it is known that such technology has not been introduced in China. Therefore, whether it is an iron wheel hub or an aluminum wheel hub, it is not recommended to repair it if it is not round, because there will still be safety hazards after repair.
