Zusammenfassung:	A pneumatic tire (100) is disclosed having a bead portion provided therein with a bead core (30, 140, 240, 300). The bead core (30, 140, 240, 300) has a central bead core portion (33, 40, 310), a first annular layer (35, 350) of a plurality of sheath wires surrounding the central bead core portion (33, 40, 310), and a second annular layer (37, 370) formed of a plurality of sheath wires surrounding the first annular layer (35, 350). The second annular layer (37, 370) of sheath wires has a diameter less than the diameter of the sheath wires of the first annular layer (35, 350).
