ABSTRACT:
A wheel rim includes an annular rim body having a horizontally disposed rim axis and an imaginary central plane that is perpendicular to the rim axis. The rim body includes a pair of annular side walls, an annular base wall, a pair of annular strengthening walls, and an annular reinforcing wall. The annular side walls are disposed respectively on opposite sides of the imaginary central plane. The annular base wall interconnects the annular side walls. Each of the annular strengthening walls extends from a respective one of the annular side walls toward the imaginary central plane and is disposed radially outward relative to the annular base wall. The reinforcing wall includes a pair of connecting segments, each of which interconnects the annular base wall and a respective one of the annular strengthening walls, and a reinforcing protruding segment that protrudes radially and outwardly relative to the rim axis.
