Abstract
An improved rim for use on a heavy, off-road vehicle formed of a tubular rim base member having a circumferential groove in the outer cylindrical surface adjacent one end thereof, the groove being of semi-circular cross-sectional configuration, a first bead flange secured at one end of the rim base member, a second bead flange slidably mounted on the other end of the rim base providing a contour substantially the same as the inner contour of the first bead flange, the second bead flange having a circumferential recess in the inside surface at the outer end thereof, and a split circular cross-sectioned locking ring removably received within the base member circumferential groove so that when the second bead flange is slidably positioned on the rim base, the locking ring can be placed in the groove and when the second flange slides outwardly the recess therein retains the locking ring within the groove and the locking ring serves to retain the second bead flange on the rim. In a preferred embodiment both the first and second bead flanges are substantially identical and the first bead flange is slidably positioned on the rim base and retained in position by an integral increased diameter circumferential seat formed as a part of the rim base, or by welding the first bead flange to the rim base.
