Abstract
A non-pneumatic tire includes a wheel hub portion, a tread ring portion, and a plurality of flexible spokes extending between and coupled to the wheel hub portion and the tread ring portion. A hollow core is positioned between adjacent flexible spokes or formed within each flexible spoke. The plurality of flexible spokes are configured to cyclically move between a narrow position to a wide position when the non-pneumatic tire is attached to a vehicle and is rolling on a road surface such that the plurality of flexible spokes act as a bellows that pumps air from one side of the non-pneumatic tire to another side of the non-pneumatic tire.
