Can the size of the wheel hub be changed?

The wheel hub is the part at the center of the wheel where the axle is installed, commonly referred to as the "rim" or "steel rim." Its size can indeed be modified. Wheel hubs are prone to accumulating dirt, and if not cleaned for extended periods, they may corrode or deform, leading to potential safety hazards. Therefore, special attention should be paid to wheel hub maintenance. The wheel hub is also known as the rim. Depending on the characteristics and requirements of different vehicle models, the surface treatment processes for wheel hubs vary, generally categorized into painting and electroplating. For standard vehicle models, wheel hubs are less focused on appearance, with good heat dissipation being a fundamental requirement. The process typically involves painting—spraying followed by baking—which is cost-effective, provides vibrant colors, and ensures long-lasting durability. Wheel hub maintenance methods: Choose the right cleaner: Household cleaners and common dishwashing detergents on the market, being either alkaline or acidic, can be highly corrosive to the wheel hub surface. Opt for a neutral soap solution to clean the wheels and avoid exposing them to strong chemical agents. When the wheel hub is at a high temperature, never wash it directly with cold water. Wait for it to cool down naturally before cleaning. Otherwise, the aluminum alloy wheel hub may be damaged, and the brake disc could deform, affecting braking performance.
Wheel size can indeed be modified. As someone who frequently engages in car modifications, upgrading from the stock 16-inch to 18-inch wheels made the visual impact more imposing and the car look sportier. However, matching issues must be considered. For instance, when increasing the wheel diameter, wider tires must be fitted accordingly to avoid rubbing against the fenders, otherwise the ride will be very bumpy over bumps. It's also essential to check the offset value to align with the brake discs, as safety is paramount. I once downsized the wheels to save fuel, but the handling deteriorated, making the car feel unstable at high speeds, and it took several days to adjust properly. After upsizing the wheels, the odometer will become inaccurate, requiring an ECU recalibration. Overall, modifications are fun, but professional shops must be consulted for safety testing. For daily driving, it's advisable not to tamper with the stock size to avoid more losses than gains. Reading forum experiences and sharing is very practical.
