Alloy Wheel
An alloy wheel is a wheel made from aluminium or magnesium alloy rather than steel.
What is Alloy Wheel?
Alloys are lighter and can improve cooling and appearance. They are cast, flow-formed or forged. They can crack or bend from potholes. Kerb scuffs are cosmetic, but cracks and bends need professional assessment; welding is often not allowed. Corrosion around the bead can cause slow leaks. Winter salt attacks unprotected alloys, so clean them regularly. Some cars require specific wheels for brake clearance.
How it works
The rim holds the tyre and the centre bolts to the hub.
Why it matters for your car
Cracks and bends cause air loss and vibration. Use matching bolts with the correct seat.
