This component secures a wheel to the apparatus during tire mounting and demounting. It typically consists of a circular or star-shaped plate with adjustable jaws that grip the wheel’s rim firmly. Different designs accommodate various wheel diameters and materials.
Proper wheel securement is essential for operator safety and prevents damage to both the wheel and the tire during service. Historically, securing wheels for tire changes was a laborious and potentially hazardous process. The development of this specialized clamping mechanism significantly improved efficiency and safety in tire shops.
