A multi-element skateboard wheel having at least two different hardness surfaces including a softer center exterior surface and a harder side exterior surface. The softer center surface is the principal weight supporting surface which, because of its lower durometer material provides a quieter and smoother ride and better traction than conventional skateboard wheels. The harder side surface, which in the preferred embodiment is positioned on each side of the wheel, comprises a higher durometer material which exhibits less frictional resistance to sliding engagement with vertical surfaces such as curbs and with high inclines and the like. Moreover, in the preferred embodiment, the harder side surfaces extend around to the radial surface of the wheel at the precise same radial height as the softer center surface.
