Apparatus for mounting and dismounting vehicle tires, comprises a disc on which the tire is releasably clamped by screw-threaded members, and means to rotate the disc about a vertical axis. A roller arranged generally radially of the axis of the tire, with the axis of the roller horizontal, engages the bead of the tire to flex the tire for mounting and dismounting the tire from its rim. The roller is mounted for bodily vertical movement on a vertical spindle in a direction parallel to the axis of the disc on which the tire is mounted, and also for horizontal swinging movement about an axis adjacent its end remote from the axis of the tire.
