The invention relates to a toroidal inner tube (30, 130). The invention is characterized by the fact that the inner tube (30, 130) is in the form of a flexible corrugated tube (40, 140) that is curved to form a closed loop, the tube comprising alternating crest rings (46, 146) and trough rings (48, 148), the tube presenting a radius (R) and, when measured in a plane perpendicular to the axis of the tube, the radial thickness of at least one of the crest rings is less than the radial thickness of at least one of the trough rings (48, 148).
