SOLUTION: In the pneumatic tire, at least carcass layer 12 and a plurality of belt layers are disposed from an inner side in a tire diametrical direction to an outer side in the tire diametrical direction. The plurality of the belt layers is structured by impregnating a three shaft fabric 13A weaving cords 13X, 13Y, 13Z arranged in three axial directions intersecting each other with a rubber ingredient. The plurality of the belt layers is structured by at least two types of a cord reinforcing layer 13 wound around a tire in a tire circumferential direction and a spiral cap 14 wound in spiral in the tire circumferential direction.
