Does Scratches on Aluminum Alloy Wheels Matter?

If the wheel hub is only scratched on the surface, it will only affect the appearance and will not impact the performance of the car tires. However, if the scratch exposes the primer, attention is needed as the scratched area may wrinkle and the damage could expand over time, eventually leading to rust and corrosion. If the edge of the wheel hub is scratched, it should be repaired promptly to prevent the tire from losing airtight contact, which could cause air leakage. Here are some related details: 1. Methods: Gravity casting, forging, and low-pressure precision casting are the three main methods for manufacturing aluminum alloy wheels. 2. Advantages: Gravity casting is cost-effective and highly productive, but the finished products are prone to bubbles, uneven density, and insufficient surface smoothness. Forged products, while of higher quality, have higher manufacturing costs and lower yield rates. Low-pressure precision casting offers excellent formability, clear contours, uniform density, smooth surfaces, controllable costs, and high yield rates, making it the primary method for manufacturing aluminum alloy wheels today.

Minor scratches on aluminum alloy wheels are generally not a big issue, mostly affecting the appearance rather than functionality. It's common to accidentally scrape against curbs or small stones while driving daily. Light scratches may look unsightly but don't compromise driving safety – you can restore the shine by polishing them with toothpaste or fine sandpaper. Deep scratches that reach the wheel edge might cause air leaks, so check if the tire pressure remains stable and prevent rainwater from corroding the coating. Wheel repair kits are affordable, available online for just tens of yuan per set, making DIY repairs cost-effective. Overall, minor scratches can be overlooked; for serious damage, visit a professional shop for repainting or replacement to ensure wheel reliability while driving. When parking, maintain proper distance to protect the wheels and keep your mood untarnished.

Aluminum alloy wheel scratches require attention to depth and location. If it's just a surface scratch, it has almost no impact on vehicle performance. We've encountered this countless times over ten years of driving, and a bit of wheel paint can cover it up. However, deep scratches near the tire edge may compromise the seal, leading to slow leaks or accelerated wheel corrosion, posing safety risks. I recommend immediately checking tire pressure and wheel condition. Prevention is simple: avoid parking near lane edges and install wheel protectors. Minor damage is cheap to repair and can be done yourself; severe deformation requires replacement to avoid affecting driving safety—don't delay treatment.

Wheel scratches are minor issues, but the key is to assess the depth of the damage. For shallow scratches, you can buy a wheel repair paste to smooth and repaint them, which takes about half an hour. Deep scratches may corrode the wheel coating, leading to air leakage or unstable tire pressure. Don’t rush to replace them; professional shops can fix them for a few hundred dollars. When parking, avoid potholes to protect the wheels, as long-term exposure can worsen the problem.
