Abstract
A molded plastic wheel includes a seamless annular body that is integrally molded from a first material exhibiting a first density and includes a hollow hub having an axle bore and hollow spokes that radially extend from the hub to a hollow box defined by planar first and second side wall surfaces, which extend from the spokes substantially orthogonal to a tread surface that lies parallel to the axle bore. Cavities of the hub, the spokes, and the box communicate with each other. A tread piece having a channel shape with first and second side pieces projects substantially orthogonal to a connecting tread band. The tread piece is separately molded from a second material exhibiting a second density different from the first material. The tread piece is stretch fitted over the box such that the tread band overlies the tread surface and the side pieces abut the side wall surfaces.
