Beschreibung
Zusammenfassung:	A pneumatic tire having an air impermeable layer. A film formed of a thermoplastic resin or thermoplastic elastomer composition comprising a blend of a thermoplastic resin and an elastomer is used for the air impermeable layer. Separation of the film is prevented and an inner appearance of the tire is improved. The air impermeable layer 10, which is disposed on the inner side of the tire, is formed from a laminated body 14 comprising a ribbon-shaped film 11 and ribbon-shaped elastomer plies 12 and 13 laminated on opposite sides thereof. The laminated body 14 is wound in the circumferential direction of the tire in such a partially overlapping manner that it is displaced at prescribed intervals. Each pair of adjacent wound portions 14A and 14B of the laminated body 14 are spliced to each other in a partially overlapping manner in a state where the ribbon-shaped film 11 is disengaged from itself.
