Abstract
A two-piece tire rim is prepared from a molded, one-piece wheel casting which is generally cup-shaped in configuration. The casting, which is open at one end and closed at its opposite end, has an inner annular recess formed coaxially in the inner surface of its closed end, and has formed coaxially in its outer peripheral surface an external annular recess radially spaced from, and in axial registry with an internal annular recess. The casting is separated into two separate sections by cutting through the casting in a circular path extending from the external annular recess to the internal annular recess, thereby producing a generally annular shaped inner rim section, and a generally disc-shaped outer rim section. The two rim sections are then machined to final form, and are secured together to form the desired two-piece tire rim.
