Abstract
Nearly circular, generally C-shaped beadlocks, which are made from a generally rigid plastic material, are slightly flexible so that they can be inserted within a tubeless tire and snugly around the annular central section of a supporting tire rim of either the split rim or drop center variety. The confronting ends of the C-shaped beadlocks are secured together by releasable clips, which function to prevent the ends of the beadlock from separating during use at high speeds or at low speeds in run flat operation. At least certain embodiments of the beadlocks have a plurality of spaced ribs projecting from each side thereof to engage and retain the beads of a tire against dislodgment of a rim.
