Does Wheel Hub Polishing Affect Safety?
2 Answers
Wheel hub polishing does not affect safety. Its main impact on the vehicle is that it accelerates the oxidation of the wheel hub, causes black spots, and makes it easier for dirt to adhere, making it harder to clean. Additionally, wheel hub polishing is a technique used for modifying and repairing wheel hubs, primarily involving the creation of linear patterns on the hub surface using various grinding products. Polished wheel hubs become more aesthetically pleasing and three-dimensional, and can also appropriately extend the lifespan of the wheel hub. Solutions for wear on polished wheel hubs are as follows: 1. Sanding: First, use water sandpaper to smooth out the scratches, then proceed with further sanding while wet. Be mindful of the pressure during sanding to avoid causing artificial damage. If dirt is noticed during the sanding process, clean it promptly before continuing. 2. Filler: After thorough sanding, apply an appropriate amount of filler to the scratches, keeping the thickness under 2 millimeters. Wait a few hours after application, then use 1000-grit water sandpaper for further sanding. During this process, carefully inspect for any uneven areas and perform secondary repairs as needed.
As someone who has been in auto repair for over a decade, I believe wheel rim polishing does pose safety risks. Polishing involves grinding and buffing the surface of the rim to make it shinier, but this process can potentially damage the metal structure of the rim, such as thinning the material thickness or causing internal stress changes. Once the strength of the rim is compromised, it may deform or even crack during high-speed driving, leading to vehicle misalignment or tire blowouts. I've also encountered cases where customers experienced noticeable vibrations due to imbalance after modifications. It's advisable to always go to professional shops that use appropriate equipment and avoid cheap roadside stalls to save money. Additionally, regularly inspect the condition of your rims, and if you notice any abnormal corrosion or scratches, address them promptly. Factory rims undergo rigorous testing, so avoid unnecessary modifications.
