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 rear surface has a relatively smooth profile and the front 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.

    L'invention concerne un disque de roue comprenant un moyeu situé au centre à l'intérieur du disque de roue et définissant un axe de roue. Le disque de roue comprend en outre un bord circonférentiel externe et une partie de transition s'étendant radialement entre le moyeu et le bord circonférentiel externe. La partie de transition comporte une surface avant et une surface arrière de sorte que la surface arrière ait un profil relativement lisse et que la surface avant comporte une pluralité de courbures de forme annulaire concentriques façonnées en son sein, ce qui permet d'obtenir la partie de transition ayant une épaisseur variable entre les surfaces avant et arrière.
