Abstract

A pneumatic tire including an inner liner made of a polymer sheet is made of a polymer composition. The polymer composition includes a polymer component of a styrene-isobutylene-styrene triblock copolymer by 5 mass % to 40 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 20 mass % to 95 mass %, and sulfur by 0.1 mass parts to 5 mass parts with respect to the polymer component by 100 mass parts. The polymer sheet has a thickness of 1.6 mm to 4.0 mm. A tread is made of a rubber composition including carbon black by 60 mass parts to 200 mass parts with respect to 100 mass parts of a rubber component including styrene-butadiene rubber by greater than or equal to 50 mass %.
