Strip, method for manufacturing the same, and method for manufacturing pneumatic tire

A method for manufacturing a pneumatic tire in which a strip is wound spirally on a cylindrical drum such that a strip main body forms overlapping portions to form an inner liner, and the inner liner is disposed on an inner surface of a raw tire, and then vulcanization is performed wherein,

• said strip being formed of composite layers of
• (A) a first layer made of a styrene-isobutylene-styrene (SIBS) triblock copolymer, and
• (B) a second layer comprising:
• (b1) a layer made of a styrene-isoprene-styrene (SIS) triblock copolymer;
• and
• (b2) a layer made of a styrene-isobutylene (SIB) diblock copolymer containing at least one additive selected from the group consisting of stearic acid, zinc oxide, antioxidant, vulcanization accelerator, and sulfur, and disposed adjacently to a carcass ply,
• said strip further having ear portions on opposite sides of the strip main body,
• said strip main body having a thickness of 0.05 mm to 1.0 mm, and
• said ear portions having a thickness thinner than the thickness of said strip main body and a width of 0.5 mm to 5.0 mm.
