AbstractA wheel adapted to be rotated about a normally horizontal axis perpendicular to a normal direction of travel has a hub centered on the axis and a central core body made of a hard material and coaxially surrounding the hub. This core body has an annular outer surface centered on and turned radially away from the axis and having a pair of axially opposite edges. A pair of similar side-wall bodies of a soft material symmetrically flank and are joined to the core body and each have an annular surface having a radial outer edge joining the core body at a respective one of the edges thereof and a radial inner edge at the hub. The surfaces of the side-wall bodies curve continuously from their outer edges to their inner edges.
