At what level of wheel rim damage should it not be used?

Assess the degree of deformation and fracture of the wheel rim. 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: 1. If the wheel rim has only suffered minor impact with no significant effect on the suspension, it may still be usable. For more severe impacts, take the vehicle to a repair shop for inspection, including a four-wheel alignment check. 2. Hitting a curb can affect the tire, wheel rim, suspension, and shock absorbers. Severe impacts may damage the tire, causing sidewall bulges, blowouts, or wheel rim deformation, and could even harm the suspension, leading to body deformation and unusual noises while driving.

I always end up hitting my rims while driving, like scraping against the curb when parking, which leaves scratches or small dents on the surface. However, if the rim's dent depth exceeds 2 millimeters, or if you see obvious cracks, it absolutely shouldn't be used anymore. Severely deformed rims can cause the wheel to lose its roundness, leading to intense vibrations at high speeds and making the tire more prone to bursting. Once, I felt my car shaking violently on the highway, and upon inspection, it turned out to be a balance issue caused by a deformed rim. The mechanic said such damage can't be fully repaired and requires a replacement. As a car owner, I suggest checking with the naked eye immediately after any impact—if it's uneven or has cracks, don't take the risk; safety is no small matter. Also, pay attention to the condition of your rims during regular maintenance to avoid bigger problems.

As a driver who frequently takes long-distance trips, I'm not too worried about minor dents or scratches on the wheel rims, but it depends on the severity. Small scuffs or shallow dents are nothing to worry about and can be ignored to save both money and hassle. However, if the rim has deep dents or cracks that affect wheel balance, causing noticeable steering wheel vibrations or uneven tire wear, it's a different story. I've experienced this myself—after ignoring a small dent, I later found the rim deformed when replacing tires, requiring a full replacement at a much higher cost than repair. From an economic standpoint, if the damage is severe enough that repair costs approach the price of a new rim, or if structural integrity can't be guaranteed, it's better to replace it. I'd opt for a new wheel to ensure reliable performance on the road, as safety and durability are more important. Don't skimp on wheel rims to avoid bigger troubles down the road.

As a veteran driver with over a decade of experience, I've seen plenty of wheel rim damage. The key is to inspect the surface: minor scratches are harmless, but if you spot fine cracks or deep dents that look like impacts, replace them immediately. A friend once ignored a small dent, then experienced severe wheel wobble on the highway before a tire blowout. Mechanics say rims become unsafe when deformation exceeds tolerance. I always run my hand over the surface – any unevenness or rough edges means trouble. Never gamble with wheel integrity. Damage is easy to diagnose, so replace without hesitation when needed. Safe driving lies in the details.
