Because of the particularity of the steel rim hub, the hub maintenance here mainly refers to the alloy hub.
If the vehicle has just run on the road, do not wash the wheel hub immediately, because the temperature of the wheel hub will increase with the temperature rise of the tire and the use of the brake during driving. It is recommended to stop for a period of time and clean the wheel hub after the temperature drops.
The wheel hub is very close to the road surface and the brake disc, so the wheel hub is often the part that is easy to get dirty. It is usually the dirt thrown up by the road surface and the powder left by the brake disc after braking. It is recommended not to use a hard brush to clean it. It is easy to remove the dirt attached to it with a special cleaning fluid and a soft brush.
When driving, pay attention to avoid potholes, and slow down when passing the speed hump. In particular, if the steel rim hub passes through the potholes quickly, it is possible to change the steel rim into irreversible deformation. Once deformation occurs, the body may jump when driving at high speed, affecting the driving stability of the vehicle. Although alloy wheel hub is not easy to deform, once there is slight deformation, vehicle dynamic balance is required, and the wheel hub needs to be replaced when the deformation is serious.
Don't park the vehicle for a long time. It is recommended to move the vehicle properly every week to prevent wheel hub deformation and irreversible tire deformation.
