ABSTRACT:
A pneumatic tire and a tire and wheel rim assembly are disclosed in which the tire has means preventing the tire remaining inflated when fitted to a non-matching wheel rim.
The tire has a pair of axially spaced tire beads at least one of which has a circumferentially extending toe projecting axially and radially inwards of the bead. The toe has primary air relief means extending between axially inner and outer surfaces of the toe to prevent the toe effecting a seal with the rim bead seat or hump when the tire is fitted to a non-matching wheel rim.
The tire bead having the toe may have secondary air relief means axially outboard of the primary air relief means to prevent the tire bead effecting a seal with the bead retaining flange when the tire is fitted to a non-matching wheel rim.
