ABSTRACT:
A safety wheel rim for use with pneumatic tires has a removable band which is securable so as to obstruct the mouth of the well used to receive the beads of a tire when fitting the tire onto the rim. The band can thus be locked against radial expansion regardless of the position of the tire beads so that the beads cannot accidentally enter the well in the event of deflation of the tire while travelling. The well may be offset from the median plane of the rim and also spaced from the bead-retaining flanges. Examples of the securing means for the band shown are an inflation valve stem which is screw-threaded through the outer of overlapping ends of the band and which cannot be inflated unless the band is secured, and screws arranged to tighten the band circumferentially.
