Abstract:
A pneumatic tire includes an inner liner layer formed from a laminate sheet obtained by laminating: a sheet made from a thermoplastic resin or a thermoplastic resin composition which is a blend of the thermoplastic resin and an elastomer; and a rubber bonded by curing to the thermoplastic resin or the thermoplastic resin composition. The pneumatic tire avoids occurrence of cracks near a splice portion of the inner liner layer after the pneumatic tire starts to be used for driving, and thereby achieves excellent durability. In the tire, an inner liner layer is formed by lap-splicing end portions of a laminate sheet which is obtained by the laminating A sheet with end portions each having a tip subjected to a tip sharpening process is used as the sheet made from the thermoplastic resin or the thermoplastic resin composition which is the blend of the thermoplastic resin and the elastomer.
