PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of enhancing grounding performance and steering stability while maintaining lateral rigidity at least to an conventional degree. SOLUTION: This pneumatic tire includes: a first carcass layer 4A, comprised of a main body 4A1 located in a bead core 5, of which both ends are turned back from the inside to the outside of the tire and extend to a side wall 2 and a turned-back portion 4A2 located at a turned-back portion of the bead core 5; and a second carcass layer 4B arranged adjacent to the outside of the first carcass layer 4A. A reinforced cord f1 located in the main body 4A1 of the first carcass layer 4A and a reinforced cord fb located in the second carcass layer 4B are inclined in the same direction relative to a tire radial direction TR. A reinforced cord f2 located at a turned-back portion 4A2 of the first carcass layer 4A is reversely inclined to reinforced cords f1, fb for the main body 4A1 and the second carcass layer 4B, relative to the tire radial direction TR.
