ABSTRACT A coupling system for releasable coupling of one or more extra wheels to the original wheels of a vehicle comprises a cylindrical annular plate arranged to abut upon a tire edge or the like at the rim edge of the original wheel and the rim edge of the extra wheel, and of a number of locking cams fastened to the original rim and distributed in the peripheral direction of the wheels. The cams are arranged to interlock with tightening hooks fastened to the annular plate. The extra wheel can be attached to the annular plate by spot welding. In the annular plate outwardly open cut- outs are made opposite each tightening hook. When mounting the annular plate with the attached extra wheel the cutouts are led in over the locking cam fastened to the original rim and then the extra wheel and the annular plate are tur- ned in the peripheral direction of the wheels whilst the edge of the annular plate abuts the tire edge on the origi- nal rim. When the annular plate is turned sufficiently in the peripheral direction of the wheels such that the tigh- tening devices are opposite the locking cams, the tighte- ning devices are tightened in engagement with the locking cams.
