Does a small chip on the wheel hub require replacement?
2 Answers
If a small chip on the wheel hub can be repaired, replacement is not necessary. The wheel hub is the rotating part of the tire's inner rim connected to the wheel core via spokes, which is the metal component supporting the tire, also known as the rim, steel wheel, or wheel disc. Types include painted wheel hubs and chrome-plated wheel hubs. Maintenance methods for wheel hubs are: 1. Avoid using cold water for cleaning when the wheel hub is at a high temperature; 2. In humid environments, clean the wheel hub frequently to prevent salt corrosion on the aluminum surface. The functions of the car wheel hub are: 1. To serve as the mounting point for the axle, supporting the tire and cushioning external impacts; 2. To ensure contact between the tire and the road surface, maintaining the vehicle's driving performance.
I've seen many cases of small chips on wheel rims during my years in auto repair. Although the chip may seem minor, the rim is the core support for the tire, and structural damage can lead to serious issues. A small chip can cause wheel imbalance, leading to increased vibration while driving, and over time, it may wear out the suspension system. If the damage is on the edge or deep, it can more easily compromise the seal, causing slow tire leaks. Safety comes first—don't delay, take it to a professional shop to check for deformation using a balancing machine. If cracks or significant deformation are detected, replace the rim immediately—human life is more important than money. Whether the rim is made of aluminum alloy or steel, minor damage can accumulate fatigue, affecting high-speed handling stability.
