Damage to the wheel hub (i.e., the "hub" in the question) can indeed cause the tyre to fall off, but this needs to be judged based on the specific degree of damage. Over time, this may cause slow air leakage or even a tyre blowout, and in extreme cases, the tyre may detach from the hub. For example, edge defects caused by parking scratches or hitting potholes while driving require timely replacement of the wheel hub, while surface scratches or paint peeling can be addressed through repair. It is best to choose a 4S shop for wheel hub repair to ensure workmanship standards, but if structural damage is involved (such as cracks or large-area metal loss), a new wheel hub must be replaced to eliminate safety hazards. During daily driving, collisions between the wheel hub and hard objects should be avoided, and regular inspection of the wheel hub's condition can prevent such risks.
