They are typically made of metal or plastic and are circular in shape, resembling a ring. It’s important to note that trim rings are typically used on steel wheels rather than alloy wheels. Alloy wheels often have their own decorative designs or finishes that do not require trim rings. Additionally, trim rings are optional accessories and are not a necessary component for the proper functioning of the wheels.
