摘要： A pneumatic tire using as an air permeation prevention layer a film consisting of thermoplastic resin or thermoplastic elastomer composition obtained by blending thermoplastic resin with elastomer, wherein the film is prevented form being peeled off to prevent entry of a release agent into the interior and the internal view of the tire is improved. An air permeation prevention layer (10) disposed on the inner side of the tire is constituted of a laminate (14) obtained by layering ribbon-form elastomer layers (12, 13) on the opposite sides of a ribbon-form film (11). The laminate (14) is wound in the tire circumferential direction while being overlapped partially and deviated at specified intervals. Respective adjoining winding portions (14A1, 14A2) of the laminate (14) are joined by being overlapped partially with ribbon-form films (11) kept separated from each other.
