TYRE-CHANGING MACHINE

The present invention concerns a tyre-changing machine provided with a basic structure that can rest on the ground, a retaining and rotation unit mounted on an upper part of the structure and adapted to retain and set the rim (C) of a wheel (R) in rotation around an axis of rotation of the wheel (Z-Z) and a holding column associated with the retaining and rotation unit and intended to support a tool for mounting/disassembling a tyre (P) onto/from the rim (C) of the wheel (R). Advantageously, the tool comprises a hooked end which can rotate passively around an axis of rotation (X-X) orthogonal to the axis of rotation of the wheel (Z-Z).
