    摘要： An objective of the present invention is to reduce the development of defect during vulcanization. A method for producing a pneumatic tire comprises: a carcass pl y formi ng step to cover both surfaces of a code array made of the carcass cords of the carcass ply with a topping rubber; a step of forming a raw cover including the carcass; and a step of vulcanizing the raw cover. The carcass ply forming step comprises an arranging process to intersect rubber-un-coated air-absorptive organic fiber cords with carcass cords of the carcass ply on at least one side of the carcass ply.

    摘要： [Object] To provide a pneumatic tire 34 in which weight reduction is achieved without deteriorating internal pressure maintaining performance.
    [Solution] The tire 34 includes a liner 46 located inward of a carcass 42. The liner 46 includes a first inner liner 66 extending on and between one of beads and the other of the beads and along and inward of the carcass 42; and a pair of second inner liners 68 extending from ends 62a of a belt 44, respectively, along the first inner liner 66 substantially inward in a radial direction. The second inner liners 68 are located between the first inner liner 66 and the carcass 42. The first inner liner 66 is formed by a first rubber composition being crosslinked. A base rubber of the first rubber composition includes a butyl rubber. Each second inner liner 68 is formed by a second rubber composition being crosslinked. A base rubber of the second rubber composition includes a diene rubber.
