At what level of wheel rim damage is it unusable?

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.
I believe driving safety is the top priority, and the extent of wheel rim damage determines whether it can continue to be used. If it's deformed, especially with large dents or cracks on the edges, it should be replaced immediately. I once scraped a curb, causing a slight dent in the rim. At first, I didn’t pay much attention, but at high speeds, the car started shaking. Upon inspection, I found the balance was affected. For safety reasons, I immediately went to a repair shop for a thorough check. The mechanic said even a deformation of just one or two millimeters shouldn’t be ignored, as it increases the risk of a tire blowout. It’s important to develop good driving habits—reverse slowly and avoid forcing the car onto curbs. If you hit something, don’t hesitate to replace the rim if necessary. When it comes to safety, saving money isn’t worth the risk. Regular maintenance helps detect issues early, preventing potential hazards from accumulating. I advise new car owners to take this seriously—protecting yourself ensures peace of mind.
How badly damaged can a wheel rim be before it becomes unusable? From my experience, it depends on the repair cost and risk. If it's just minor scratches or small dents, you might continue using it to avoid wasting money on a new one. However, if there's deformation or cracks, especially if it affects tire installation and balance, you must replace it—otherwise, it's dangerous and can damage your car. A friend of mine had a damaged wheel rim; repairing it would have cost a few hundred, but replacing it cost over a thousand, and he chose the latter. When driving, always watch out for potholes to save money without compromising safety. Inspect the rim's surface—if it's uneven, don't push your luck.
