Apparatus for fitting a motor vehicle tire on a disc wheel comprises a tire fitting tool mounted rotatably about an axis, an electric drive motor to drive the tire fitting tool about the axis, a current supply means for the drive motor, and a torque limiting means to terminate the rotary drive to the motor when a predetermined torque transmitted to the tire fitting tool is exceeded, thereby to protect the tire from overloading in the fitting operation.
