The fit between a wheel and a tire is improved. A tire assembly fitting device fits a bead portion of a tire of a tire assembly, including a wheel and the tire mounted on the wheel, to a bead seat portion of the wheel. The fitting device includes a support portion configured to support the tire assembly, and a pressing portion. The pressing portion is configured to press a first surface portion in a surface of at least one of sidewalls of the tire. The support portion is configured to support the tire assembly so that a second surface portion located in the surface of the sidewall on the opposite side of the rotation axis of the tire assembly from the first surface portion is displaceable in a direction away from the rim center plane of the wheel.

A tyre changing apparatus (1) comprises: a frame (10); a supporting element (11) for supporting a wheel (2) rotatably about an axis of rotation (A); an arm (12) movably connected to the frame (10) to be moved by an actuator (5B, 5B) along a direction of movement (B) parallel to the axis of rotation (A); a bead breaker tool (13) connected to the arm (12) to move between an activated position, where it is in contact with the tyre (3), and a deactivated position, where it is spaced from the tyre (3); a control unit (14). The bead breaker tool (13) includes a mounting element (13A) and a bead breaker disc (13B) which rotates freely relative to the mounting element (13A) and comprises a sensor (131), configured to generate a contact signal (132) representing a rotation of the bead breaker disc (138) relative to the mounting element (13A); the control unit (14) is connected to the sensor (131) to receive the contact signal (132).
