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).

A machine (M) for mounting and demounting a tyre (P) relative to a corresponding rim (C) of a vehicle wheel (R) comprises a wheel-holder unit (200) that is movable in rotation about a vertical axis of rotation (Y) and movable in translation along an axis of translation (X) towards and away from the machine (M). The machine (M) comprises a main arm (400) and a working unit (500) connected to the main arm (400) and including a first arm (501a) pivoted to the main arm (400) at a hinge point (F) and a first sidewall pressing tool (502a) which is configured to come into abutment against a sidewall of the tyre (P) of the wheel (R) mounted on the wheel-holder unit (200) and which is connected to the first arm (501a). The main arm (400) is movable by translation parallel to the horizontal axis of translation (X) towards and away from a column (101) to keep the hinge point (F) vertically aligned with the vertical axis of rotation (Y) of the wheel-holder unit (200), responsive to a movement in translation of the wheel-holder unit (200).
