<p>The invention relates to a method for mounting a tyre on a rim or demounting a tyre from a rim, wherein the wheel (tyre/rim assembly) is rotated by an electric motor (12) about an axis (A), wherein the motor current fed to the electric motor (12) is controlled dependent on the rotational speed and torque required for the mounting and/or demounting operation, and wherein the motor current is automatically changed to apply a high torque peak, when the measured motor current is greater than a preset limit at a low rotational speed during a preset time. Furthermore, the invention relates to an apparatus for mounting a tyre on a rim or demounting a tyre from a rim</p> |
