ABSTRACT:
An improved method for forming a vehicle wheel wherein the inboard and outboard tire bead seat retaining flanges are precisely oriented and located relative to an inboard mounting surface of the disc, and the inboard and outboard tire bead seat surfaces are precisely oriented and located relative to a wheel axis includes the steps of steps of: (a) providing a rim defining a rim axis and including at least an inboard portion and an outboard portion; (b) providing a disc defining a disc axis and including at least an inner annular wheel mounting portion and an outer annular portion, the wheel mounting portion defining an inboard mounting surface and having a centrally located pilot hole formed therethrough; (c) positioning the rim and disc together in generally coaxial relationship; (d) simultaneously with step (c), joining the outer annular portion of the disc to the rim by welding to produce a partially-formed wheel assembly defining a wheel axis; (e) subsequent to step (d), forming an inboard tire bead seat retaining flange, an outboard tire bead seat retaining flange, an inboard tire bead seat, and an outboard tire bead seat of the wheel to locate the inboard and outboard tire bead seat retaining flanges a predetermined first and second lateral distances, respectively, relative to the inboard mounting surface of the disc and in a parallel relationship therewith, and to locate the inboard and outboard tire bead seats a predetermined first and second radial distances, respectively, relative to the wheel axis and in a concentric relationship with the wheel axis.
