    摘要: Provided is a pneumatic tire (1) including an inner liner (9) disposed inwardly in the tire relative to a carcass ply (6) bridged between a pair of bead portions (4). The inner liner (9) is formed of a first layer (PL1) disposed inwardly in the tire and a second layer (PL2, PL3) disposed to be in contact with a rubber layer of the carcass ply (6). The first layer (PL1) is a thermoplastic elastomer composition containing a thermoplastic elastomer containing at least one of a styrene-isobutylene-styrene block copolymer and an SIBS modified copolymer having a styrene block moiety modified with acid chloride or acid anhydride having an unsaturated bond. The thermoplastic elastomer composition also contains at least one of an ultraviolet absorber and an antioxidant. The second layer (PL2, PL3) is a thermoplastic elastomer composition containing at least one of a styrene-isoprene-styrene block copolymer and a styrene-isobutylene block copolymer.
