A pneumatic tire which includes an inner liner having enhanced adhesion to a tire member that adjoins the inner liner and which hence has heightened air impermeability, reduced rolling resistance, and improved low-temperature durability, wherein the inner liner is constituted of a polymer laminate comprising a first layer that comprises SIBS and a second layer that comprises SIS and/or SIB. The first layer and/or the second layer is a polymer composition which contains a C4 polymer obtained by polymerizing a monomer having 4 carbon atoms, a lamellar clay mineral containing an organic compound intercalated thereinto, or at least one rubber ingredient selected from the group consisting of natural rubber, isoprene rubber, and butyl rubber. The second layer has been disposed so as to be in contact with the rubber layer of the carcass ply. In the inner liner, the thickness Gc thereof at the crown center position Pc is 100-500%, excluding 100%, of the thickness Ge thereof at the shoulder position Pe. |
