Will a small chip on the wheel hub affect safety?

Wheel hub chipped a small piece will not affect safety, if the wheel hub has a large gap, it will be prone to cracking to a certain extent, posing a driving safety hazard. Therefore, if the wheel hub has a large gap, it is best to repair the wheel hub. If it cannot be repaired, it is best to replace the wheel hub. The following is a partial introduction about tires: 1. Introduction: Tires are circular elastic rubber products assembled on various vehicles or machinery for ground rolling. They are usually installed on metal rims, supporting the vehicle body, cushioning external impacts, achieving contact with the road surface, and ensuring the vehicle's driving performance. 2. Required performance: Tires are often used under complex and harsh conditions, enduring various deformations, loads, forces, and high and low temperatures during driving. Therefore, they must have high load-bearing performance, traction performance, and cushioning performance. At the same time, they are also required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation.
I run a repair shop and deal with various wheel issues every day. If a small chunk is chipped off the wheel, the first thing to check is the location. If it's just on the edge and there are no cracks or deformations, slow daily driving shouldn't be a big issue. However, if the damage is at the spoke connection points or load-bearing areas, even a few millimeters of missing material can pose significant risks. Damaged aluminum alloy wheels experience internal stress imbalance and may suddenly fracture at high speeds. Last time, a car owner ignored wheel scratches, and the wheel shattered on the highway, nearly causing a rollover. I recommend immediately checking the wheel balance and roundness. If the deformation exceeds 2 millimeters, replace the wheel without hesitation—safety leaves no room for compromise.
I've been into car modifications for ten years, and I deeply understand the importance of wheels. Those seemingly minor dents are actually like planting a ticking time bomb inside the metal. Wheels bear the friction from tires and the weight of the car body, especially under the impact of bumpy roads. Once, I measured a slightly deformed wheel with a vernier caliper—the surface was only off by 0.5 millimeters, but the stress tester showed a 40% spike in peak stress. What's even scarier is that metal becomes brittle in winter's low temperatures, and the centrifugal force from high-speed cornering could tear the damaged spot at any moment. I sincerely advise you not to skimp on that thousand bucks—replace them when needed, because losing control happens in an instant.
