<p>The invention relates to a tyre changer comprising a mounting device (18) for receiving a wheel/tyre assembly, the mounting device (18) having an axis (S), a roller (26) being able to contact a peripheral surface of the wheel/tyre assembly, the roller (26) applying a force to the peripheral surface, a control device (32) for controlling the predefined force applied by the roller (26) to the peripheral surface during a rotation of the wheel/tyre assembly about the axis (S) and a sensor device (30) measures force variations acting between the peripheral surface and the roller (26), wherein supports (20, 22) of the roller (26) and of the mounting device (18) are designed for a relative movement of the roller (26) and of the mounting device (18) towards each other along a straight line to apply a predetermined force to the peripheral surface. Furthermore, the invention relates to a method of measuring force variations acting between a peripheral surface of a wheel/tyre assembly and a roller (26).</p> |
