To What Extent Does Wheel Rim Scraping Require Repair?

[VanPreston]

Wheel rim scraping requires immediate repair if deformation occurs to prevent safety hazards. Below are the treatment methods for wheel rim scraping: Wheel rim edge scraping damage: When the car wheel rotates close to the edge of the road, it is easy to damage the outer edge of the wheel rim. In such cases, professional welding technology can perfectly restore and refurbish the wheel rim. Wheel rim edge damage: If the car's wheel rim is accidentally hit by a hard object, it may cause the edge to break. Under such circumstances, the car tire must be replaced, but the wheel rim can still be perfectly restored and refurbished through welding and reshaping. Wheel rim twisting or deformation: When the car wheel rim is subjected to collision or impact, it is prone to bending or deformation of the wheel rim edge, which is considered severe damage. As long as the structure of the wheel rim is not compromised, the damaged wheel rim can be reshaped and corrected using wheel rim repair equipment and special techniques.

After driving for so many years, wheel rim scratches are all too common. To be honest, I don’t bother fixing minor scratches—they just look a bit unsightly. But there are a few cases where repairs are necessary: scratches deeper than 2 mm, the kind where your fingernail noticeably catches when you run a finger over them, need immediate attention to avoid tire damage; deformed wheel edges, even slightly warped ones, can compromise the tire seal, leading to slow leaks; and damage in the bead seat area—where the tire meets the rim—is especially dangerous. Once, my wheel had a gouge, and it leaked air slowly every time I hit a pothole, costing me 500 bucks for a rim repair. If the structure is deformed or cracked, it’s safer to just replace the wheel outright.

Friends who are into car modifications know that wheel repair depends on the extent of damage. Minor surface scratches like hairline marks are no big deal, but if the metal layer is scraped off exposing the primer, it needs repair to prevent oxidation and corrosion. If the edge is chipped—even just the size of a fingernail—like a bitten cookie, it must be fixed; otherwise, it will affect the wheel's dynamic balance, causing severe steering wheel vibration at speeds above 80 km/h. The most troublesome damage is to the wheel's flange edge—if uneven, it can wear down the tire sidewall. I've seen cases where this led to a blowout. If the wheels have been repainted, repairs should be done promptly to avoid color mismatch when touching up. It's recommended to opt for wheel refinishing (machining) during repairs for a near-new finish.

There are three levels of wheel rim scratches to determine the necessity of repair. Minor surface paint scratches can be ignored, moderate metal layer damage requires touch-up painting to prevent rust, and deep scratches exceeding 1.5mm must be repaired. Pay special attention to the wheel rim lip area: if deformation causes air leakage after tire installation (like a hissing sound after inflation); or if the rim edge is uneven, leaving gaps between the tire bead and rim after installation; or if there are sharp edges that could cut the tire. These situations all require attention. Professional repair involves first correcting the deformation, then welding the aluminum alloy to fill the gaps, and finally machining on a lathe. Avoid using putty for filling as it may detach under high temperatures.
