Is Corolla Wheel Hub Oxidation Normal?
2 Answers
Corolla wheel hub oxidation is not normal. The wheel hub is the central part of the wheel where the axle is installed, commonly referred to as the "rim" or "steel ring." Wheel hubs are prone to accumulating dirt, and if not cleaned for a long time, they may corrode and deform, posing safety hazards. Taking the 2021 Corolla Elite Edition as an example, its body dimensions are 4635mm in length, 1780mm in width, and 1455mm in height, with a wheelbase of 2700mm and a body weight of 1290kg. This car is equipped with a 1.5L naturally aspirated engine, delivering a maximum power of 89kW and a maximum torque of 148Nm, paired with a 6-speed manual transmission.
I used to drive a Toyota Corolla and also encountered wheel oxidation. In fact, some oxidation on aluminum alloy wheels is quite common, especially if you live in areas with high salt content, such as regions in the north where de-icing agents are used or coastal cities with high humidity. After three or four years of driving my car, some spots or slight discoloration appeared on the wheel surfaces, which isn't a serious issue and generally doesn't affect driving safety. The cause might be corrosion reactions triggered by moisture in the air or residual chemicals from car washes. Regular cleaning of the wheels, such as applying protective wax after washing, can prevent further deterioration. However, if you notice severe oxidation, like large areas of peeling or uneven wheels, it's best to have them checked at a repair shop to avoid affecting balance or causing long-term damage. In short, minor oxidation isn't a malfunction, and proper maintenance is all that's needed.
