PROBLEM TO BE SOLVED: To provide a pneumatic tire which has unvulcanized viscosity and vulcanized adhesiveness with an adjacent member sufficiently, is equipped with an inner liner having an excellent air shielding property and has excellent grip performance and steering stability.SOLUTION: There is provided a pneumatic tire equipped with an inner liner composed of a polymer sheet, wherein the polymer sheet is composed of a polymer composition. The polymer composition includes a polymer component including 5 mass% or more and 40 mass% or less of a styrene-isobutylene-styrene triblock copolymer and 60 mass% or more and 95 mass% or less of at least one rubber component selected from the group consisting of natural rubber, isobutylene rubber and butyl rubber. The polymer composition contains 0.1 pts.mass or more and 5 pts.mass or less of sulfur based on 100 pts.mass of the polymer component. The polymer sheet has a thickness of 1.6 mm or more and 4.0 mm or less. A tread of the pneumatic tire is composed of a rubber composition containing 60 pts.mass or more and 200 pts.mass or less of carbon black based on 100 pts.mass of a rubber component containing 50 mass.% or more of styrene-butadiene rubber. |
