<p><P>PROBLEM TO BE SOLVED: To secure rigidity of a bead part and to improve uniformity. <P>SOLUTION: A pneumatic tire 1 includes a carcass 6 which comprises a folded ply 6A having a body part 6a, a core inside part 6b and a raised part 6c. The bead part 4 comprises a bead reinforcing rubber 10 which is elongated inward and outward in the axial direction of the tire at least in a radial-direction-of-tire internal area of the core inside part 6b of the folded ply 6A. The bead reinforcing rubber 10 comprises a toe-side rubber part 11 which is disposed on the axial inside of the tire, and a heel-side rubber part 12 which is disposed on the axial-direction-of-tire outside of the toe-side rubber part 11. The toe-side rubber part 11 is made of a rubber material more rigid than the heel-side rubber part 12. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
