• wherein said first flange of said rim base includes a radially extending, axially inboard surface axially opposing said radially extending side surface of said first side ring and a circumferentially extending surface radially contacting said tapered surface of said circumferentially extending inner surface of said first side ring,
• wherein said circumferentially extending surface of said first flange and said tapered surface of said circumferentially extending inner surface of said first side ring are inclined radially outwardly in an axially outboard direction of said multi-piece rim.
