PROBLEM TO BE SOLVED: To provide a lightweight pneumatic tire excellent in air permeability without damaging a moldability. SOLUTION: The pneumatic tire uses a film of thermoplastic elastomer which has the air permeability of 25×10<SP>-12</SP>cm<SP>3</SP>cm/cm<SP>2</SP>sec cmHg or less, and a residual elongation percentage after elongation in a room temperature of 45% or less, preferably of 1 to 25% for an inner liner.
