(57) [Problem] To provide a pneumatic tire capable of simplifying a manufacturing process, reducing manufacturing costs, and improving durability by eliminating twisted cords. SOLUTION: A tire skeleton member 4 extending between a pair of right and left bead portions 3 is composed of a plurality of types of polymer materials from a tread portion 1 to a bead portion 3 without using a twisted cord. At least two composite layers 4X and 4Y are formed in the member 4 by arranging a plurality of polymer material layers having different Young's moduli in parallel, and the composite layers 4X and 4Y are formed. 4Y are arranged so that the orientation direction is inclined with respect to the tire circumferential direction and intersect each other between the layers, and the tread layer 6 is laminated on the outer periphery of the tire frame member 4. |
