The invention relates to a green pneumatic tire and discloses a green pneumatic tire comprising a tire cavity; first and second sidewalls extending respectively from first and second tire bead regions to a tire tread region; and a cable embedded into a rubber material of the green tire for allowing a creation of an air passageway in the tire after curing the green tire in a tire mold is disclosed. The cable comprises a core of a first material and a shell of a second material, wherein the shell surrounds the core. Also, a method of manufacturing a pneumatic tire comprising an air passageway is disclosed. The method comprises the steps of: providing such a green pneumatic tire; curing the green tire together with the cable in a tire mold; and extracting the core of the cable from the cured tire thereby providing an air passageway in the tire.
