Abstract
A process for manufacturing a vehicle wheel includes the steps of preparing a wheel raw material blank in which rim raw material is integrally formed at a peripheral edge of a disk member. The rim portion is formed by spinning the rim raw material while rotating the wheel material about the axis of the disk member. Thereafter, such spin molded raw material is heat treated, and then machined by cutting. The center portion of the rim is spin formed to its final thickness while the rim edge portions are left with a thickness after spin molding that requires machine cutting to the final dimensions.
