Abstract

A pneumatic tire including an inner liner made of a polymer sheet is provided, and the polymer sheet is made of a polymer composition. The polymer composition includes a polymer component of a styrene-isobutylene-styrene triblock copolymer by greater than or equal to 5 mass % and less than or equal to 80 mass %, and a rubber component of at least one kind selected from the group consisting of natural rubber, isoprene rubber, and isobutylene-isoprene rubber by greater than or equal to 20 mass % and less than or equal to 95 mass %. The polymer composition includes sulfur by greater than or equal to 0.1 mass parts and less than or equal to 5 mass parts with respect to the polymer component by 100 mass parts. The polymer sheet has a thickness Tof 0.6 mm<T≤4.0 mm.
