Abstract
This improved bead locking apparatus and system is based on the provision of an expandable single and/or dual bead lock device with a bead compression ring that thrusts against the bead(s) of tire from the inside and is braced against and via the drop center of the wheel rim and/or an opposing bead compression ring. The aforesaid ring or rings are caused to press against the tire bead(s) via mechanical means actuated by a screw driver or similar implement. In single bead lock designs, the said implement can be inserted between the bead and rim on the side of the wheel opposite from that where the compression ring is located. In other designs, the said implement is inserted through an opening in the rim (which is preferably located in the drop center area of the rim) that is sealed with an O-ring, valve or plug. The bead lock designs of the invention may also be advantageously combined with a run flat ring in order to further facilitate the objects of the invention in assisting and enabling run flat capabilities.
