Abstract
In a pneumatic tire production method including a step of overlapping end portions of a sheet laminate and vulcanization-molding the tire, the sheet laminate being obtained by layering an elastomer layer and a sheet of a thermoplastic resin composition containing a thermoplastic resin or a blend of a thermoplastic resin and an elastomer, after the end portions of the sheet laminate are overlapped, the overlapped portion of the sheet laminate is compression-bonded at a temperature of not less than a glass transition temperature Tg of the thermoplastic resin and not greater than 120° C.

A pneumatic tire production method including a step of overlapping end portions of a sheet laminate and vulcanization-molding the tire, the sheet laminate consisting of two layers obtained by layering a tie rubber layer and a sheet of a thermoplastic resin composition containing a thermoplastic resin or a blend of a thermoplastic resin and an elastomer, wherein the sheet of the thermoplastic resin composition containing the thermoplastic resin or the blend of the thermoplastic resin and the elastomer contains at least nylon, the pneumatic tire production method comprising the step of:
- after the end portions of the sheet laminate are overlapped by contacting the sheet of the thermoplastic resin composition and the tie rubber layer with each other,
- compression-bonding the end portions of the sheet laminate at a temperature of not less than a glass transition temperature Tg of the thermoplastic resin and less than 80° C., at a duration of not less than 1 second and not greater than 30 seconds, and at a pressure of not less than 0.2 MPa and not greater than 1 MPa by pressing a fiber-reinforced rubber bladder onto the overlapped portion from a direction perpendicular to a plane of the overlapped portion.
