<P>PROBLEM TO BE SOLVED: To provide an unvulcanized tire having an inner liner which achieves improvement in uniformity and internal-pressure retention performance of a tire by effectively preventing joint cracking, likely to occur during molding or after molding, in order to flexibly correspond even to the tire size having a high inner expansion coefficient while contributing to the cost reduction by effectively utilizing the existing equipment, and a pneumatic tire. <P>SOLUTION: The unvulcanized tire is manufactured by a method including a process in which an inner liner, comprising a laminate having a resin layer and a rubber layer, is wound around a molding drum while overlappingly joining the other end of the inner liner onto one end of the inner liner at both ends of the inner liner. Before joining the one end and the other end to each other, one piece of the rubber layer is previously arranged on the sidewall of the one end. <P>COPYRIGHT: (C)2012,JPO&INPIT |
