ABSTRACT:
The wheel is made up of first and second annular wheel portions comprised respectively of low and high coefficient of friction materials; for example, urethane and rubber. These annular portions are bonded together in coaxial relationship. The outer peripheral edges are provided with a calculated radius to aid the transition of a skateboard or roller skate on which the wheel is mounted over surfaces encountered in pools, bowls, skateboard or roller skate parks, ground ridges and the like. Further, the first annular wheel portion of urethane includes a hub coaxially extending within the second annular portion of rubber, the radius of the outer peripheral edge of the second annular portion comprising the rubber curving inwardly to cover the outer peripheral edge portion of the hub to thereby inhibit separation of the first and second wheel portions.
