A wire wheel (10) is provided in which some of the array (13) of spokes extending between the hub (11) and the rim (12) penetrate the latter in the outboard bead seat (16). This bead seat (16) is of smaller diameter than the inboard bead seat (17) but is covered by a ribbon (21) of a plastics material the outer diameter of which corresponds to that of the bead seat (17). The plastics ribbon (21) is trapped in the channel of the outboard bead seat (16) and seals the spoke holes penetrating the outboard bead seat (16). Nevertheless a metal step (23) is exposed above the plastics ribbon (21) for abutment by the toe of the outboard tyre bead (not shown). <IMAGE>
