Rims, also known as wheels, are load-bearing components that connect to the vehicle’s axles and support the tires. They are utilized on all wheel positions and directly impact vehicle handling and braking performance. Construction typically involves steel or aluminum alloy, formed into a circular profile with a mounting surface for tire bead retention. Key technical features include diameter, width, offset, bolt pattern, and center bore, all of which must match vehicle specifications. Rims are designed to withstand dynamic loads, radial forces, and corrosion, with variations existing for different vehicle types and performance levels.
