A wheel disc for vehicle wheels manufactured by flow forming, in particular for passenger cars, which has a stretched disc transition surface subsequently provided with ventilation holes and a radial outer disc edge. All ventilation holes are located in the transition surface and are attached by punching or cutting. In order to improve the competitiveness of vehicle wheels made of steel or other materials suitable in particular for cold forming compared to cast vehicle wheels made of aluminium, the transition surface is provided with several changes in material thickness generated during flow forming by displacement of the tool and, viewed in the radial direction, effecting a wave structure on the surface facing the tool during flow forming. The surface provided with the wave structure can in particular form the non-visible inner side of a vehicle wheel, but can also form the visible side. In addition, the opposite surface can also be provided with a wave structure.

A wheel disc includes a hub located centrally within the wheel disc and defining a wheel axis. The wheel disc further includes an outer circumferential edge and a transition portion radially extending between the hub and the outer circumferential edge. The transition portion has a front surface and a rear surface such that the front surface has a relatively smooth profile and the rear surface has a plurality of concentric ring-shaped curvatures formed therein, thereby providing the transition portion with a variable thickness between the front and rear surfaces.
