发明名称 PNEUMATIC TIRE
摘要 <p>This pneumatic tire has an inner liner that is formed of a polymer laminate. The polymer laminate comprises a first layer which is formed of a first polymer A composition containing SIBS and has a thickness of from 0.05 mm to 0.8 mm (inclusive) and a second layer that is formed of a second polymer A composition containing SIS and/or SIB and has a thickness of from 0.01 mm to 0.8 mm (inclusive). The first polymer A composition and/or the second polymer A composition contains an epoxidized styrene-butadiene-styrene triblock copolymer in an amount of from 0.5% by mass to 40% by mass (inclusive). The second layer is arranged so as to be in contact with a rubber layer of a carcass ply. With respect to the inner liner, the thickness (Ge) thereof at the shoulder position (Pe) is larger than the thickness (Gc) thereof at the crown center position (Pc), and the thickness (Ge) is from 0.2 mm to 1.9 mm (inclusive).</p>
