An apparatus for driving a motor vehicle wheel while it is fitted to the motor vehicle for detecting unbalance thereof comprises a friction wheel which is driven by a drive motor and which is pressed against the motor vehicle wheel for driving same at a speed required for measuring its unbalance. The drive motor is switched on or off in dependence on the pressure force with which the friction wheel is pressed against the motor vehicle wheel, in such a way that no slip occurs between the friction wheel and the motor vehicle wheel.
