The broken aluminum alloy rim is basically beyond repair. If you hit it with a hammer, it will crack. If it is baked with a blowtorch, you can knock it slowly. But there is no guarantee that the tire will not be used if it bubbles. If the wire is broken, it will be dangerous when it is used. If the rim is not round, it will definitely affect the dynamic balance. Therefore, it is recommended to replace the hub tires.
