Abstract

A multi-part automotive wheel comprises first and second wheel discs having first and second mating surfaces, respectively, where the first and second discs are to be joined to each other. An annular radial groove is disposed on one of the first and second surfaces for receiving an O-ring for sealing the first surface in respect of the second surface. The groove includes a substantially radial basewall and first and second sidewalls which extend from the basewall toward an intermediate section and from the section toward both edges of the groove, the edges defining a radial groove opening which is smaller than a distance between the sidewalls at the section such that an O-ring having a larger cross-sectional diameter larger than the opening will be retained within the groove prior to the discs being joined together. The basewall merges with the first and second sidewalls with rounded corners to reduce concentration of stress at the corners.
