<p>A pulley wheel tyre comprises a body (11) moulded from hard-wearing plastics material and a plastics insert (20) moulded in the body (11). The body has a groove (16) for receiving a rope and the insert is radially spaced inwardly of the groove. The insert has a different colour from the body so as to provide a visual indication of wear. The insert may be made of relatively resilient material to cushion the body in the groove.</p>
