The invention relates to a wheel disc for a disc wheel, in particular for commercial vehicles, with an at least essentially radially extending hub connection flange (11) and with an essentially cylindrical disc rim (13) which can be connected to a wheel rim (14) and with a transition region (16) extending between the disc rim (13) and the hub connection flange (11). In order to improve such a wheel disc and a disc wheel provided therewith in such a way that, on the one hand, a lowest possible weight of the wheel can be realized, but on the other hand, also the strength requirements placed on the wheel disc or on the disc wheel provided therewith are reliably fulfilled, the invention suggests that the transition area (16) is provided with ventilation holes (17) distributed over the circumference, wherein the ventilation holes (17) extend in the radial direction from a first inner pitch circle (18) located closer to the connection flange (11) to a second outer pitch circle (19) located closer to the disc rim (13) of the wheel disc, wherein the transition region (16) in the radial section in a first sectional area (24) extending between the hub connection flange (11) and the radially inner first pitch circle (18) has a material thickness (DA) reduced by at least 30% compared to a material thickness (DN) of the hub connection flange (11) and/or wherein the ventilation holes (17) have a hole region with a hole width (b) increasing in the circumferential direction of the disc from the radially inner, first pitch circle (18) towards the radially outer, second pitch circle (19). The wheel disc according to the invention, the special design of which was developed by elaborate finite element methods, is characterized on the one hand by a particularly advantageous material thickness distribution of the disc wall and on the other hand by a special design and arrangement of the ventilation holes that are provided in the transition region of the wheel disc between the hub connection flange and the disc rim.
