An annular inner-tube (14) is securedly positioned between the inner wheel (12) and the first ring (16). A second ring (18) has a radially outer surface (46) and a radially inner surface (44) adapted to mate with first ring (16). A tread (20) is secured to radially outer surface (46) of said second ring (18).
