Abstract:
The present invention relates to a ribbon-shaped strip used for an inner liner and a method for manufacturing the strip. The strip is to be wound on an outer circumferential surface of a tire molding drum or a core body to form an inner liner. The strip has an inner layer disposed inwardly in a tire and an outer layer disposed outwardly in the tire. The inner layer and the outer layer are bonded to each other with their ends offset by 0.5 mm to 30 mm in a widthwise direction. At least one layer of the inner layer is formed of an elastomer composition containing a styrene-isobutylene-styrene block copolymer. At least one layer of the outer layer is formed of a thermoplastic elastomer composition.
