DEVICE FOR MOUNTING AND UNMOUNTING GIANT TIRES

摘要

A device facilitating the mounting and unmounting of a giant pneumatic tire on a wheel comprises a pair of arms pivoted about a pin and a screw by which the distance between the arms can be adjusted. One of the arms rests against the inner side of a flange of a side ring and the other arm rests against an associated conical ring by which a bead of the tire is supported. One of the arms has an adjustable extension by which it can push on the rim well of the wheel. Adjustment of this extension facilitates an axial pull on the side ring and conical ring towards the outside of the wheel. One of the arms also preferably has a second adjustable extension by which it can pull on the rim well. Adjustment of the second adjustable extension facilitates an axial push on the side ring and conical ring towards the inside of the wheel.
