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.

From my experience in car maintenance, wheel oxidation is quite common. The aluminum alloy wheels on a Corolla, when exposed to the environment for a long time, undergo chemical reactions that lead to surface corrosion, especially in humid or rainy areas. Minor oxidation is actually normal and not considered a defect, but if the roads are salted or you frequently wash your car with strong acidic cleaners, the problem can accelerate. I would recommend first checking the extent of oxidation: small spots are fine, but feel with your hand to see if it's rough; if there's large-scale discoloration or the wheel is deformed, there might be hidden risks. To prevent it, I make it a habit to dry the wheels immediately after washing the car, not letting water stagnate. In the long run, avoiding parking in puddles or using wheel covers can reduce the risk, but if it's severe, it's best to seek professional repair.

As a new Corolla owner, I was a bit worried when I noticed some oxidation on the wheel rims. I heard that rim corrosion could affect both appearance and even safety, but my friend who runs an auto repair shop said it's normal for aluminum alloy rims to oxidize naturally after prolonged outdoor use, and it's not a big deal. Unless there's wheel wobbling or surface cracking, there's no need for concern. In my case, there are light-colored patches on the wheel edges, and after wiping off some dust during car washing, they look fine. I'd suggest owners like me to regularly check the tires, especially after driving in rainy seasons or dusty areas. For mild oxidation, just keep them clean and prevent dust buildup; if there are issues, visit a shop for advice. In short, don't stress too much—normal usage shouldn't cause major problems.
