Businesses in the alloy wheels category supply wheels made from aluminium-based alloys for cars and other vehicles. They typically offer wheels in different diameters, widths, designs and finishes, with options intended to suit particular vehicle makes and models. Staff can help customers check compatibility, including wheel fitment, bolt pattern, offset and load rating. Some businesses also supply related items such as wheel nuts, locking bolts, centre caps and tyre pressure monitoring equipment. Services may include fitting wheels and tyres, balancing, and checking that the wheels are correctly secured and clear of vehicle components. Specialist repairers can assess damage such as kerbing, bends, cracks or corrosion, and may offer straightening, welding where appropriate, refinishing, repainting or diamond-cut refurbishment. The type of repair available depends on the wheel's condition and construction; badly damaged wheels may be unsuitable for repair.
