Provided is a pneumatic tire provided with an inner liner comprising a polymer sheet, wherein the polymer sheet comprises a polymer composition. The polymer composition includes, as polymer constituents, 5-40% by mass of a styrene-isobutylene-styrene triblock copolymer and 60-95% by mass of at least one rubber constituent selected from the group consisting of natural rubber, isoprene rubber, and butyl rubber, and the polymer composition includes 0.1-5 parts by mass of sulfur relative to 100 parts by mass of the polymer constituents. The polymer sheet has a thickness of 1.6-4.0 mm. A tread comprises a rubber composition including 60-200 parts by mass of carbon black relative to 100 parts by mass of a rubber composition containing at least 50% by mass of styrene-butadiene rubber.
