1. Apparatus for mounting a tyre on a rim of a wheel and/or for removing a tyre from a rim of a wheel of a vehicle, comprising:
a base having a support for receiving and rotating the wheel;
a frame joined to the base and having an upright with a longitudinal axis substantially parallel to an axis of rotation of the wheel;
a support arm associated with the upright and movable in a direction substantially parallel to the axis of rotation of the wheel;
a tool for operating on the wheel, said tool being mounted on the support arm;
a pneumatic actuator able to move the support arm along the direction substantially parallel to the axis of rotation of the wheel, the pneumatic actuator comprising a piston sliding inside a jacket defining therein a first chamber upstream of the piston and a second chamber downstream of the piston;
characterized in that at least one pressure sensor is associated with said pneumatic actuator, wherein:
said at least one pressure sensor is configured to determine a first pressure relating to the first chamber and a second pressure relating to the second chamber,
said at least one pressure sensor is able to send a signal representing contact between the tool and the wheel to a control unit,
the control unit is able to control the actuator and a further actuator associated with the support arm to move the tool along a trajectory determined by the control unit, depending on the signal representing the contact between the tool and the wheel,
the further actuator is a pneumatic actuator for pivoting the tool relative to the support arm about an axis perpendicular to the axis of rotation of the wheel,
the trajectory determined by the control unit comprises pivoting the tool, and
the tool is a bead breaker disc.
