A profiled wheel rim (1) has at least in the wheel inner side an internal rim corner (2), whereby on the wheel outer side it is welded with a disk (5). The disk (5) has on its circumference regularly distributed a plurality of venting holes (6) and its outer marginal region lying in radial direction behind the venting holes (6) is performed as a free surface (7). The wheel rim (1) outer marginal region adjacent to the wheel outer side bearing concentric against the disk (5) and being formed by the free surface (7) extending nearly radially and in the direction toward the wheel center, passes in the wheel hub (Ý) region through a region (8), that is curved in the form of the letter "S", whereby the weld (12, 13, 15, 18, 20, 24, 25) between the wheel rim (1) and the disk (5) is arranged immediately within the region of the outer rim corner (4).
