Abstract
Abstract A wheel structure is disclosed suitable for material handling equipment. The wheel has a metal rim with a solid tire of plastic material molded thereon. Dislodgement of the tire from the rim is positively prevented by penetration of the tire material into one or more circumferential grooves in the rim and into lateral holes in the rim which communicate with such groove or grooves to provide an interlock between the tire and the rim.
