<p><P>PROBLEM TO BE SOLVED: To provide a tire having improved durability. <P>SOLUTION: A tire is provided that is made using a cord as a reinforcing material obtained by polyester filaments twisted together and processed by an adhesive composition. A polyester filament is a fiber made of polyester having specific intrinsic viscosity containing ethylene terephthalate as a main repeating unit, and formed of a polyester fiber in which a terminal carboxy group amount in the fiber and a long period by small-angle X-ray diffraction each fall within a specific range, and a surface treatment agent having an epoxy group adheres to the surface of the fiber. The adhesive composition includes a specific thermoplastic high molecular weight polymer, a specific water-soluble polymer, a compound selected from a reaction product of diphenylmethane diisocyanate and a thermal dissociation type blocking agent for an isocyanate group and the like, and an aliphatic epoxide compound. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
