Abstract

A welded vehicle wheel having a sectional rim which is connected to a nave or wheel disk in the area of the drop center by means of a weld seam, and which has standardized sections, in particular rim flange and bead seat area in terms of their axial and/or radial extent, transition radii and angles, and nonstandardized sections, in particular drop center area. Here, a nonstandardized section has at least one cambered part which reinforces the rim and extends radially and over the entire circumference, the center axis of the cambered part being coaxial with the axis of the rim and being located outside the usual rim section
