<p>The present invention relates to a bead breaker group comprising a support (2,5) and at least one bead breaker tool (3) mounted for rotation around a pin (4), said tool being substantially flat and comprising:
- at least one portion configured as an abutment front (3b,3d,3f) against a flange of a rim of a tired wheel to be bead broken; and
- at least one portion having curved peripheral edge substantially coaxial with the pin (4) and intended to act as an engagement-penetration zone (3a,3c,3e) between the flange of a rim and the bead of a tire to be bead broken,
the distance between the abutment front (3b,3d,3f) and the pin (4) being less than the distance between the pin (4) and the at least one engagement-penetration zone (3a,3c,3e).</p> |
