ABSTRACT:
A bead lock including an insert casing and a bead spacer for providing an air passageway in a vehicle tire to be mounted on a wheel rim on which is located an insert valve and a rim lip for retention of the vehicle tire bead, the insert casing including an insert bead adapted to push against the tire bead and to hold the tire bead firmly against the inner surface of the rim lip, the inner wall of the vehicle tire and the outer surface of the insert casing defining an internal tire space to be pressurized for inflation of the vehicle tire or depressurized for the deflation of the vehicle tire via the insert valve, the tire bead and the insert bead interposed between the internal tire space and the insert valve, the bead spacer extending from the insert bead to an insert valve area corresponding in use to the insert valve location whereby to define at least one air passage for communication of the internal tire space with the insert valve, wherein the bead spacer is made of material sufficiently flexible to substantially conform to the contours of the wheel rim and sufficiently incompressible to provide the air passageway.
