Abstract:
Provided are a pneumatic tire and a manufacturing method of the same capable of improving a separation failure at end portions of an inner liner layer made of either a thermoplastic resin or a thermoplastic elastomer composition. The pneumatic tire includes an inner liner layer made of either a thermoplastic resin or a thermoplastic elastomer composition obtained by blending a thermoplastic resin component and an elastomer component. The inner liner layer is provided on an inner side of the tire so as to face a tire cavity. A recessed portion is formed in an internal surface area of the tire where an end portion of the inner liner layer is located.
