Abstract

A welded vehicle wheel includes a center or wheel disc and a rim. The center has a side wall area at an outermost circumference of the wheel disc having an increasing diameter toward an inner side of the welded vehicle wheel. A substantially axially disposed circumferential portion is connected to the inner end of the side wall area. The rim includes a bed region with a decreasing diameter toward the outer side of the welded vehicle wheel. In the assembled state, the rim is connected to the center by a press fit between the outer side of the circumferential portion and the bed region and by a welded seam between the free-end of the circumferential portion and the bed region. The press fit and welded seam form a space therebetween that is circumferentially continuous and expands in cross-section toward the inner side of the welded vehicle wheel.
