Title: PNEUMATIC TIRE AND METHOD FOR PRODUCING SAME
Abstract:
The purpose of the present invention is to provide a pneumatic tire and a method for producing the same with which it is possible to improve dimensional stability, the low-loss property, and durability. A pneumatic tire in which a rubber-fiber composite that has rubber and fiber cord comprising polyamide multifilament fibers in which the glass transition temperature is 150-200°C is used in a carcass ply and/or a cap ply, wherein the pneumatic tire is characterized in that a layer comprising a resorcinol-formalin-latex adhesive is present at the interface of the rubber and the fiber cord, and the heat-shrinkage stress at 177°C of the fiber cord on which the layer is formed is 0.01-0.2 cN/dtex.
