ABSTRACT:
The invention relates to a tire-demounting device with two bead-breaking elements pivoted on a holder that is placed upon the tire. The demounting device is in the form of a pair of pincers, with the bearing points of the bead-breaking elements being at different distances relative to the pivot of the pincers. With the pincers open, the first bead-breaking element exerts a force component which is substantially radial relative to the wheel and when further opened, the second bead-breaking element exerts a force component which is substantially axial relative to the wheel.
