ABSTRACT:
An improved method for producing a full face fabricated vehicle wheel is disclosed, wherein a full face disc is formed by combining stamping and flow spinning operations. The method includes the steps of: (a) providing a generally circular rim defining an axis and including a generally axially extending well and a pair of opposed ends, one of the ends including an inboard tire bead seat retaining flange and an inboard tire bead seat, and the other end including an outboard tire bead seat; (b) providing a generally circular disc blank including an inner annular portion defining a wheel mounting surface; (c) stamping the disc blank to form an intermediate annular portion having a predetermined contour and an outer annular portion; (d) flow spinning the outer annular portion of the disc to form an outboard tire bead seat retaining flange of the full face wheel; (e) positioning the outboard tire bead seat retaining flange of the disc adjacent the outboard tire bead seat of the rim; and (f) securing the rim and disc together to produce the full face fabricated wheel.
