1. A tyre changer, comprising: a mounting device for receiving at least a wheel rim of a wheel/tyre assembly, the mounting device having an axis,a roller being able to contact a peripheral surface of the wheel/tyre assembly and to apply a predetermined force to the peripheral surface of the wheel/tyre assembly,a control device for controlling the predetermined force applied by the roller during a rotation of the wheel/tyre assembly about the axis of the mounting device anda sensor device for measuring force variations acting between the peripheral surface of the wheel/tyre assembly and the roller,wherein supports of the roller and of the mounting device are designed for a relative movement of the roller and of the mounting device towards each other along a straight line to apply the predetermined force to the peripheral surface of the wheel/tyre assembly,wherein the mounting device and/or the roller are driven by a linear drive, especially by an electro mechanic drive to apply the predetermined force onto the peripheral surface of the wheel/tyre assembly, andwherein the linear drive includes self-locking mechanical means transmitting movement and connected rigidly to the mounting device and the roller to establish the locking means. 2. A tyre changer, comprising: a mounting device for receiving at least a wheel rim of a wheel/tyre assembly, the mounting device having an axis,a roller being able to contact a peripheral surface of the wheel/tyre assembly and to apply a predetermined force to the peripheral surface of the wheel/tyre assembly,a control device for controlling the predetermined force applied by the roller during a rotation of the wheel/tyre assembly about the axis of the mounting device anda sensor device for measuring force variations acting between the peripheral surface of the wheel/tyre assembly and the roller,wherein supports of the roller and of the mounting device are designed for a relative movement of the roller and of the mounting device towards each other along a straight line to apply the predetermined force to the peripheral surface of the wheel/tyre assembly, andwherein the sensor device is connected to or includes calibration means designed to determine an absolute value of the force acting between the peripheral surface of the wheel/tyre assembly and the roller. 3. A method of measuring force variations acting between a peripheral surface of a wheel/tyre assembly and a roller, in which the wheel/tyre assembly is mounted on a mounting device of a tyre changer, the mounting device having an axis, wherein the roller and the wheel/tyre assembly are moved relatively towards each other along a straight line to apply a controlled predetermined force to a peripheral surface of the wheel/tyre assembly and force variations acting between the peripheral surface and the roller are measured, while the wheel/tyre assembly is rotated about the axis, wherein an electrical signal which is proportional to the measured force variations is produced and calibrated to determine absolute values of the measured forces. 4. A method of measuring force variations acting between a peripheral surface of a wheel/tyre assembly and a roller, in which the wheel/tyre assembly is mounted on a mounting device of a tyre changer, the mounting device having an axis wherein the roller and the wheel/tyre assembly are moved relatively towards each other along a straight line to apply a controlled predetermined force to a peripheral surface of the wheel/tyre assembly and force variations acting between the peripheral surface and the roller are measured, while the wheel/tyre assembly is rotated about the axis, wherein the lateral runout of at least one tyre side wall is determined, andwherein the lateral runout is measured with different inflation pressures of the tyre. 5. A method according to claim 4, wherein the lateral runout is measured each at an angular position at which the roller engages the peripheral surface of the wheel/tyre assembly.
