PROBLEM TO BE SOLVED: To provide a pneumatic tire which suppresses deterioration of the air leakage preventing performance by imparting a good heat radiation effect to an inner liner even after vulcanization molding of the tire and reduces the rigidity by reducing the rigidity of the film constituting the inner liner to decrease the spring constant of the tire.SOLUTION: A pneumatic tire uses a film composed of a thermoplastic resin or a blend of a thermoplastic resin with an elastomer as an inner liner 10. In the region between right and left bead filler 16 tops, the inner liner is thinner in parts of 30-80% of the total surface area of the inner liner in the region than in other parts in the region. The thickness of the parts where the inner liner is thinner is equal to or greater than 5% and smaller than 70% of the thickness in other parts. |
