Abstract
A multi-piece rim type disk wheel includes a multi-piece rim and a disk. The multi-piece rim includes a rim base, a bead seat band, a lock ring and a flange. The disk includes an outside portion constituting a part of the rim base, and a hub coupling portion extending radially inwardly from the outside portion and has a substantially T-shaped cross-section. A method of producing the multi-piece rim type disk wheel includes the steps of: manufacturing a gutter band, a first center band, a disk having a substantially T-shaped cross-section, a second center band and a back flange separately from each other; and connecting them to each other by a full penetration butt weld to form into the integral rim base.
