Patent ID: 8092627

Claim:
A manufacturing method for a pneumatic tire including the steps of: shaping a cylindrical film formed of a thermoplastic resin or a thermoplastic elastomer composite in which a thermoplastic resin is blended with an elastomer, folding the film into a sheet shape, laminating rubber layers on both surfaces of the folded film, opening the laminate of the film and the rubber layers into a cylindrical shape, fitting the laminate thus opened on a tire making drum, forming an uncured tire including the film as an air permeation preventing layer, and curing the uncured tire, the method wherein when the rubber layers are laminated on the both surfaces of the folded film, positions of the rubber layers in a width direction are displaced from each other such that an end portion of one of the rubber layers is arranged to protrude from an end portion of the film and an end portion of the other one of the rubber layers is arranged on an inner side, in the width direction, of the protruding end portion of the one of the rubber layers, so that the protruding end portion of the one of the rubber layers is caused to cover the end portion of the other one of the rubber layers in a state where the laminate is fitted on the tire making drum.
