Safety wheel

A safety wheel apparatus employing, a tubeless tire mounted on a rim about the periphery thereof, said rim being formed with flange members;

• an air chamber defined by said rim and said tubeless tire, a bead stopper disposed within said air chamber for gripping portions of said tubeless tire in cooperation with said flange members to contain bead portions of said tire against axial displacement relative to said rim;
• said bead stopper being defined by a plurality of interconnected rigid circular bead stopper units, one of at least a pair of said interconnected bead stopper units being formed at one end with a male connecting section having connecting pins, and another end thereof formed with a female connecting section having hook-like locking concave portions, said locking concave portions and connecting pins of said female and male section respectively, being disengageably connected to each other, wherein:
• said bead stopper units are flexibly connected in a radial direction thereof so as to form an endless configuation with an inner peripheral surface thereof fitted into a rim base of said rim;
• said rim being further defined by an outboard section with a body portion formed by a base of narrow width and a first flange member integrally formed along an outer edge of said portion and an inboard section with a body portion formed by a base of a width greater than said body portion of said outboard section and a second flange member integrally formed along an outer edge of said inboard body portion, said outboard and inboard portions being respectively affixed to one another by bolt means to enable cooperative placement with said bead stopper.
