<P>PROBLEM TO BE SOLVED: To provide a pneumatic tire and a manufacturing method which enables the effective inhibition of crack initiation from a junction of an inner liner rubber sheet strip and the improvement of pneumatic holdout and durability without inviting disadvantage to productivity or cost. <P>SOLUTION: The inner liner rubber sheet strip 22 is rolled in the periphery of a molding drum D, the radial internal surface of a trailer E2 is piled up and joined to the radial outside surface of a leader E1 of the roll. In the inner liner rubber strip 22 before rolling, a starting end surface S1 is made to be a slant face inclining in the trailer side toward the outside surface side, and a termination surface S2 is made to be a slant face inclining in the leader side. Angles α and β of the starting end surface S1 and a termination surface S2 to the vertical plane are to be 85° or less and 5-85° respectively. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
