How severe must wheel rim damage be to render it unusable?

Assess the degree of wheel rim deformation and fracture. If the wheel rim is dented or cracked, place the tire on a balancing machine for testing. If the tire exhibits bouncing phenomena, it should no longer be used. Below are relevant details: 1. Impact severity: Minor impacts to the wheel rim generally don't significantly affect the suspension. For more severe collisions, visit a repair shop for inspection, including four-wheel alignment checks. 2. Hitting curbs: Collisions with curbs can affect the tire, wheel rim, suspension, and shock absorbers. Severe impacts may damage the tire, causing sidewall bulges, blowouts, or wheel rim deformation. Suspension damage could lead to body deformation and abnormal noises during driving.
Whether a scratched wheel can still be used depends on the severity of the damage. Generally, minor scratches or small dents do not affect functionality, and refinishing the wheel surface can restore its appearance. However, if the wheel is visibly deformed, such as having a bend exceeding 5 millimeters at the edge, it must be replaced. Deformation may lead to tire leaks, causing the vehicle to shake or even lose control while driving, posing the highest safety risk. Additionally, if the wheel has cracks, especially deep ones extending from the inside out, it is absolutely unsafe to continue using it. I've seen many car owners ignore such minor damage, only to experience a high-speed tire blowout later. It's recommended to measure the wheel's flatness with a straight ruler during each maintenance check and consult a professional shop if any concerns arise. Never compromise safety to save money—safety comes first.
