A pneumatic tire includes film layers of thermoplastic resin or thermoplastic elastomer composition made by blending an elastomer with the thermoplastic resin, which are superposed by winding the film layer in the circumferential direction of the tire multiple times, a thickness of the film layer is in a range of 0.02 mm to 0.2 mm and a thickness of the rubber layer is in a range of 0.1 mm to 1.2 mm, and the tire wherein a rubber film is interposed between the film layers. The pneumatic tire is produced by preparing a laminated body in which the rubber layer is stuck to at least one surface of the film layer; interposing the rubber layer between the film layers by winding the laminated body in the circumferential direction of the tire multiple times; forming an uncured tire which includes the film layers and the rubber layers; and curing the tire.
A pneumatic tire which includes film layers superposed by winding a film layer in a circumferential direction of the tire a plurality of times prior to curing and radially expanding the pneumatic tire into a toroidal shape, the film layer being made of any one of a thermoplastic resin and a thermoplastic elastomer composition obtained by blending an elastomer with a thermoplastic resin, wherein an uncured rubber layer is stuck to at least one surface of the film layer to prepare a laminated body, the laminated body including the film layer is wound continuously in the circumferential direction of the tire the plurality of times such that the rubber layer of one winding of the laminated body is interposed between the film layer of the one winding and the film layer of an adjacent winding of the laminated body, and for each winding of the laminated body the film layer is the same and covers the same area of the tire,
A process for producing a pneumatic tire comprising the steps of:
