Abstract
An elongate air tube is positioned within a tire sidewall cavity in contacting internal engagement with the tire sidewall to form an assembly. The air tube includes an internal elongate air passageway and wing projections projecting in opposite directions at an axially inward body portion. The wing projections seat within cavity pockets to retain the air tube within the cavity. The air tube body operatively compresses responsive to impinging stress forces from the tire sidewall against the air tube body, whereby the air tube body reconfiguring from an expanded unstressed configuration into a compressed configuration to constrict the air passageway. The air tube body decompresses into the expanded configuration upon reduction of the impinging stress forces against the air tube body.
