A pneumatic tire which is provided with an inner liner that is composed of a polymer sheet which is formed of a polymer composition. This polymer composition contains, as a polymer component, from 5% by mass to 80% by mass (inclusive) of a styrene-isobutylene-styrene triblock copolymer, while containing from 20% by mass to 95% by mass (inclusive) of at least one rubber component that is selected from the group consisting of natural rubbers, isoprene rubbers and butyl rubbers. This polymer composition contains from 0.1 part by mass to 5 parts by mass (inclusive) of sulfur per 100 parts by mass of the polymer component. The polymer sheet has a thickness (T1) satisfying 0.6 mm; T1 <= 4.0 mm.
