<P>PROBLEM TO BE SOLVED: To provide a pneumatic tire having an inner liner which is excellent in air-barrier properties and adhesion properties to an adjacent rubber so as to reduce bladder-rubbing-breakage in vulcanization. <P>SOLUTION: The pneumatic tire includes the inner liner on the tire interior side. The inner liner is formed of a polymer laminated body constituted by a first layer of 0.05-0.6 mm in thickness made of a styrene-isobutylene-styrene triblock copolymer and a second layer of 0.01-0.3 mm in thickness containing at least either of the styrene-isoprene-styrene triblock copolymer and styrene-isobutylene diblock copolymer. In the pneumatic tire, the second layer is arranged in contact with a rubber layer of a carcass ply, and a protection layer of 0.01-1.0 mm in thickness is arranged adjacent to the inner liner in the range of plus and minus 0.04H with respect to the position of 0.2H vertically from the bead toe of tire section height H. <P>COPYRIGHT: (C)2012,JPO&INPIT |
