wheel discolouration

**Wheel discolouration** refers to a change or alteration in the original color or finish of a vehicle’s wheel (rim). This can occur due to factors such as brake dust buildup, heat from braking, corrosion, chemical reactions with road salts or cleaners, oxidation, or prolonged exposure to environmental elements. It may appear as staining, darkening, fading, yellowing, or patchy marks on the wheel surface.
