Abstract

A machine for fitting and removing the wheel tires of vehicles comprises a base frame with a turntable for gripping and rotating a rim of wheels for vehicles with at least a retention flange and a bead of a tire to be fitted on, or removed from, the rim; an operating head is operatively associated with the base frame, and is positionable near the retention flange. The operating head includes a guiding nut for the bead; a guiding wing for the bead; a grip tool for gripping the bead which is arranged between the guiding nut and the guiding wing, and includes a shaped active extremity with an oblique profile suitable for cooperating with the guiding nut for guiding the bead. Actuator assembly moves the grip tool between a first guiding configuration of the bead, in which the active extremity is arranged near the guiding nut and near the guiding wing, and a second grip configuration of the bead. The actuator assembly moves the grip tool from the first configuration to the second configuration along a first trajectory and from the second configuration to the first configuration along a second trajectory, substantially different from the first trajectory.
