PROBLEM TO BE SOLVED: To provide an air-filled tire which can reduce a load noise. SOLUTION: In an air-filled tire including a carcass ply 6A extended to a pair of right/left bead parts 4 to be folded back further with chords juxtaposed, the bead part 4 has a first bead core 9A and a second bead core 9B arranged concentrically through 8 cushion rubber layer 10 in the tire radial direction outside of this first bead core 9A further with a sectional area larger than the first bead core, and the carcass ply 6A, passing around the second bead core 9B between its radial direction inner side surface and the cushion rubber layer 10, is folded back to be locked. |
