ABSTRACT:
A vehicle wheel with a roll-formed rim has an interior rim section and axially spaced first and second beadseat sections. A disc is attached at its skirt flange to the first beadseat section. The first beadseat section has radially outward and radially inward surfaces, both angled radially outward from the wheel axis for example at a fifteen degree angle. A roll-formed groove is formed in the radially inward surface of the first beadseat section, the groove having an inwardly facing cylindrical first surface. The skirt flange has an outwardly facing cylindrical first surface, which engages and is press-fit with the groove cylindrical first surface. The skirt flange and rim are then welded. The groove has a second frusto-conical surface adjacent the groove cylindrical surface. The skirt flange may have a second frusto-conical surface to mate with the groove second frusto-conical surface. The skirt flange may have a third frusto-conical surface to mate with the radially inward surface of the first beadseat section.
