Claim 1
Independent Claim
188 words
In combination: a. a wheel rim, including a rim base, a pair of annular flanges extending from opposing sides of the rim base, and an annular bead seat adjacent each side flange; b. a tire mounted on the wheel rim such that the beads of the tire are seated on the bead seats adjacent the side flanges; and c. a plurality of clips spaced around the side flanges for retaining the beads of the tire on the bead seats, each of the clips comprising; I. a rigid fastener interlockingly engaging an adjacent side flange; II. a rigid stop interlockingly engaging an adjacent toe of the tire bead; and III. an inextensible strap connecting the fastener and stop, the strap being between the bead of the tire and adjacent bead seat and side flange of the wheel rim, at least the portion of the strap adjacent the bead seat being substantially more flexible than a like strap portion which is solid and composed of the material of the rigid fastener and stop, the strap portion being highly resistant to fatigue caused by repeated flexing thereof as the tire flexes.
