    摘要: A pneumatic tire in which, in employing as an air-impermeable layer a film formed of a thermoplastic resin or a thermoplastic elastomer component obtained by blending a thermoplastic resin with an elastomer, separation of the film during tire production is prevented; and a process for producing the same. The pneumatic tire is obtained by disposing a film closer to a tire cavity than a carcass layer, disposing a first rubber layer closer to the tire cavity than the film so as to cover the film, and disposing ends, in the width direction, of the first rubber layer outward of ends, in the width direction, of the film, the film being formed of a thermoplastic resin or a thermoplastic elastomer composition obtained by blending a thermoplastic resin with an elastomer.

    摘要: A method of forming a tire innerliner having a cylindrical inner rubber layer and a cylindrical film formed of a thermoplastic resin or a thermoplastic elastomer composition having a thermoplastic resin and an elastomer blended therewith. The cylindrical film is disposed radially outwardly of the cylindrical inner rubber layer. The method includes the following steps: wrapping an unvulcanized rubber layer cylindrically around a building drum to form the cylindrical inner rubber layer; and subsequently wrapping a sheet-shaped film formed of a thermoplastic resin or a thermoplastic elastomer composition having a thermoplastic resin and an elastomer blended therewith cylindrically around the cylindrical inner rubber layer, which is already wrapped around the building drum, to form the cylindrical film. The unvulcanized rubber layer constituting the cylindrical inner rubber layer is a strip-shaped rubber layer, and the cylindrical inner rubber layer is formed by spirally winding the strip-shaped rubber layer.
