摘要： PROBLEM TO BE SOLVED: To provide a pneumatic tire which can make durability improvement highly compatible with weight reduction in the bead part of a tire having a nipped bead structure.
SOLUTION: This pneumatic tire comprises a pair of bead parts 1, and a carcass ply 3 coating a ply cord 2 with rubber and extending between a pair of bead parts in a toroid-like manner. A pair of bead cores 5, 6 constituted by bundling bead wires 4, 5 extending in an approximately peripheral direction and positioned on inner and outer face sides of a radial carcass ply respectively are embedded in the bead part 1. A reinforcing layer 7 made of an organic fiber cord and rubber is located between the carcass ply 3 and at least one of the bead cores 5 and 6. The reinforcing layer 7 is preferably made by coating a plurality of cords 8 parallel arranged in a direction crossing with a tire peripheral direction C with rubber, and an angle α formed by the cords 8 and the tire peripheral direction is preferably within a range of 30°-70°.
