PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of raising the degree of freedom of a design and enabling the design of diversified performances when reducing the weight or troubles by obtaining an integrated structure of a carcass layer with a belt layer. SOLUTION: A reciprocal route which extends from a bead 3 to an end area of a tread 1 in the tire radial direction, extends from the end area diagonally in the tire circumferential direction to an end area on the opposite side of the tread 1, and returns to the bead in the tire radial direction from the end area forms a unit shape P. An integrated structure 40 of a carcass layer 4 with a belt layer 5 is formed by repeatedly arraying unit shapes P in the tire circumferential direction, and the integrated structures 40 are independently arranged on right and left sides of the tire so that the belt layers are overlapped with each other.
