The bead breaking unit includes: a bead breaking arm having a substantially horizontal longitudinal direction, a first extremity hinged to the base frame of a tire changing machine around a substantially vertical rotation axis and an opposite second extremity having a bead breaking tool; an operating actuator for moving the bead breaking arm interposed between the base frame and the bead breaking arm; and a control lever, associated with the bead breaking arm in proximity of the second extremity for controlling the operating actuator, wherein the control lever is hinged around an oscillation axis substantially horizontal and parallel to the longitudinal direction and is associated with return elements for maintaining the control lever in a substantially vertical balance position, the actuator being controlled in a first direction for bead breaking the tire when the control lever is rotated towards the wheel starting from the balance position.

A debeading device for tire changing machines includes a swing arm having a hinging end hinged to a base of a tire changing machine and swinging in a swing plane between an active debeading position toward the base and an inactive position away from the base; a debeading tool supported at a free end of the arm, opposite to the hinging end; an actuator for reciprocatingly rotating the arm between the active and inactive positions, which includes an externally screw-threaded member supported by the base and rotatably actuated by a motor and screwingly/unscrewingly engaged in a matingly threaded hollow member associated with the arm.

A tire removal assembly includes a press that has a base and an actuator. The base may be positioned on a support surface and the actuator is spaced from the base.

The actuator may be fluidly coupled to an air source thereby facilitating the actuator to move downwardly with respect to the base. The actuator is biased to move upwardly with respect to the base. The press may have a tire positioned between the base and the actuator thereby facilitating the actuator to engage the tire such that the actuator breaks a bead on the tire.
