To improve low temperature durability while suppressing lowering of gas barrier property.SOLUTION: A thermoplastic elastomer composition containing a continuous phase containing a thermoplastic resin and a dispersion phase containing a crosslinked rubber contains liquid polybutadiene. The thermoplastic elastomer composition is obtained by kneading a thermoplastic resin, a rubber and liquid polybutadiene with a crosslinking agent, and dynamically crosslinking the rubber. A pneumatic tire has a low air permeable film formed from the thermoplastic elastomer composition.SELECTED DRAWING: None
