PROBLEM TO BE SOLVED: To provide a pneumatic tire improved in durability of a bead part.SOLUTION: The pneumatic tire comprises a carcass constituted of a carcass main body and a carcass folding part, where in a reference state, a position in a tire radial direction of an end part of the carcass folding part is set in a range within ± 10% of a tire cross section height SH in the tire radial direction with the tire maximum width position as a center; and has reinforcing layers made of at least one layer organic fiber cord provided at an outside in a tire width direction of the carcass folding part. In the reference state, each of innermost points in the tire radial direction of the reinforcing layers made of the at least one layer of organic fiber cord is positioned further inside in the tire radial direction than the center of gravity of a bead core, and a cord of the reinforcing layer, closest to the carcass, of the reinforcing layers made of the at least one layer of organic fabric cord and a ply cord of a carcass ply of the carcass folding part are inclined in the same direction from inside toward outside in the tire radial direction. |
