The present invention improves tire uniformity and the adhesion between an inner liner and a carcass ply, and reduces crack growth accompanying repeated bending deformation during tire travelling. The strip is for forming the inner liner having a shape that is close to the finished cross-sectional shape of the tire by being wrapped in the circumferential direction of the outer surface of a core body. The strip comprises a single layer provided with a first layer disposed at the innermost layer of the tire, or comprises a composite layer of the first layer and a second layer comprising a thermoplastic elastomer composition disposed adjacent to the carcass ply. The first layer is a thermoplastic elastomer composition containing, in a styrene-isobutylene-styrene block copolymer, at least one of a tackifier, butyl rubber, and natural rubber. The strip has a strip body having a thickness (T1) of 0.02-1.0 mm, and ears formed on both sides of the strip body at a thickness (T2) that is less than the strip body thickness (T1) and having a width (W2) of 0.5 mm to 5.0 mm. |
