At what level of wheel rim damage is it unusable?
2 Answers
Assess the degree of wheel rim deformation and fracture. If the wheel rim is deformed or fractured due to impact, place the tire on a balancing machine for testing. If the tire exhibits bouncing, it should no longer be used. Below are relevant details: If the wheel rim has only suffered minor impact without significant effects on the suspension, it may still be usable. However, for severe impacts, it is necessary to visit a repair shop for inspection, including a four-wheel alignment check. Hitting the curb can affect the tire, wheel rim, suspension, and shock absorbers. In serious cases, it may damage the tire, causing sidewall bulges, blowouts, or wheel rim deformation. It could also harm the suspension, leading to body deformation and unusual noises while driving.
The usability of a damaged wheel hub primarily depends on the extent of deformation and damage. Having run an auto repair shop for over a decade, I've seen countless cases. When a hub shows significant dents or cracks, never try to make do, as this compromises tire seal integrity, leading to air leaks or even blowouts. Edge deformations are especially dangerous—they cause instability and increased risk at highway speeds. I recall a customer who ignored a small dent in his hub and ended up with a flat tire after hitting a pothole. My advice: inspect hubs immediately after impact by visually checking and running your hand over the surface for irregularities, then visit a professional shop for balancing machine tests. Minor scratches are harmless, but deformations exceeding 3mm require replacement. Avoid curbs while driving to protect hubs and save money. Regular maintenance checks are equally crucial.
