<p>A pneumatic tire includes an inner liner disposed inwardly in the tire relative to a carcass ply bridged between a pair of bead portions, the inner liner being formed of a first layer disposed inwardly in the tire, and a second layer disposed in contact with a rubber layer of the carcass ply, the first layer being a thermoplastic elastomer composition mainly containing a styrene-isobutylene-styrene block copolymer, the second layer being a styrene-based thermoplastic elastomer composition, (a) at least one of the thermoplastic elastomer compositions of the first and second layers containing a tackifier by 0.1 part by mass to 100 parts by mass relative to 100 parts by mass of the thermoplastic elastomer, or (b) the second layer containing the styrene-isobutylene-styrene block copolymer by 10 mass % to 80 mass % relative to a thermoplastic elastomer component thereof.</p> |
