<p>A wheel is produced by forming a nylon moulding which comprises a rim portion (10), hub portion (11) and webs (17) extending between the hub portion and the rim portion and then moulding an elastomeric composition in the spaces between the webs. The rim portion and the hub portion are more rigid than is the intermediate portion of the wheel and the intermediate portion absorbs shocks and reduces the transmission of sound from the rim portion to the hub portion. <IMAGE></p> |
