A pneumatic tire is provided which enables durability thereof to be improved by preventing oxidation degradation of belt layers. In the pneumatic tire, a carcass layer is laid between a pair of bead portions so that the carcass layer links the bead portions, an air penetration preventing layer is disposed on the inner surface of the tire along the carcass layer, and belt layers are buried in a tread portion at the side of the outer periphery of the carcass layer. In the pneumatic tire, a cord layer, which is formed by repeatedly winding a cord in the tire circumferential direction, is disposed between the carcass layer and the belt layers, and at least one portion of the cord layer is made close to the outer surface of the tire so that a distance between the cord and the outer surface of the tire is not longer than 2 mm.
