Abstract

A wheel rim assembly comprising a generally cylindrical rim base and a flange ring including a bead seat retained at one axial end of the rim base by a split locking ring. A T-shaped lug on the flange ring captures the ends of the locking ring in a corresponding groove on the rim base and prevents removal of the locking and flange rings when a tire mounted on the wheel rim is inflated. Circumferential grooves on the inside surface of the tire bead seat cooperate with an annular seal in the rim base to prevent inflation of a tire mounted on the wheel rim when the flange ring and bead seat are improperly positioned thereon.
