Abstract
A blowout preventing device is disclosed for attachment to vehicle wheels which have axially-elongated slots for receiving inner tube inflation stems. The device comprises a rigid filler piece which has a central portion for filling the slot and a circumferentially enlarged outer retainer portion which prevents radially inward displacement of the filler piece. An inner retainer means clamps the central portion to the inner face of the rim to prevent the device from falling into the tire in the event of deflation of the inner tube. Associated with the inner retainer means is a gripping means for engaging an inflation stem to prevent it from falling into the tire upon deflation.
