Abstract: 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.

Abstract: A wheel disc including a hub located centrally within the wheel disc and defining a wheel axis. The hub has a plurality of bolt holes formed therein. The wheel disc further including an outer circumferential edge and a transition portion radially extending between the hub and the outer circumferential edge. The transition portion has a plurality of vent holes formed therein. The transition portion has a front surface and a rear surface defining a thickness therebetween such that the thickness of the transition portion varies in the radial direction.

Abstract: A full face fabricated vehicle wheel having a wheel attached to a wheel disc. The 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 having an outboard bead seat retaining flange, and an annular transition portion radially extending between the hub and the outer circumferential edge. The transition portion includes a plurality of vent hole regions circumferentially spaced around the transition portion about the wheel axis. At least one vent hole region includes a vent hole formed through the transition portion and defining an outer perimeter such that at least two bridging portions extend inwardly from the perimeter which subdivides the vent hole into at least three smaller holes formed through the transition portion at the at least one vent hole region.

Abstract: A wheel disc including a hub located centrally within the wheel disc and defining a wheel axis. The wheel disc further including 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 plurality of concentric ring-shaped first curvatures formed therein, and wherein the rear surface has a plurality of concentric ring-shaped second curvatures formed therein, thereby providing the transition portion with a variable thickness between the front and rear surfaces.

Abstract: A vehicle wheel includes a rim having an inner peripheral surface, and a center disc portion spaced radially inwardly from the inner peripheral surface. The center disc portion includes a body having a plurality of protruding portions separated from each other by curved recesses. The wheel further includes a plurality of structural arms with each structural arm having a first arm end attached to the inner peripheral surface of the rim at a first weld attachment interface and a second arm end received within one of the curved recesses of the body. Each of the second arm ends is attached to the center disc portion at a second weld attachment interface.
