<p><P>PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of sufficiently increasing the rigidity of a bead core against the torsional deformation in the drawing direction of a carcass cord irrespective of the contour shape of a cross section of the bead core, effectively preventing any collapse of the winding state of the bead core, and enhancing the durability of a bead part. <P>SOLUTION: A bead core 3 embedded in a bead part 2 is constituted by dispersing one or more bead cords 6. There are provided faces 9 which are mutually matched with the bead cords 6 adjacent to each other at least on a part in a cross section of the bead core 3, and the matching faces 9 are fixed at least to a part of the bead core 3 in the circumferential direction. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
