If the edge of the vacuum tire hub leaks air, it is generally caused by the deformation of the hub caused by impact or scraping; In this case, the owner can remove the tire, clean the impurities around the hub, and then polish the edge of the hub with fine sandpaper. Finally, when loading the tire, applying a little butter or other lubricating oil to the hub and tire edge can further improve the air tightness of the tire.

Car owners should also pay more attention to avoid collision with the wheel hub of the vehicle and prevent the wheel hub from deforming, so as to effectively avoid air leakage between the vacuum tire and the steel ring and reduce potential safety hazards during driving.
