Abstract

PURPOSE: To produce a pneumatic radial tire having improved durability by using a specific polyethylene terephthalate dip cord having high modulus, low heat shrinkage percentage, high strength, high fatigue resistance, high heat resistance as a reinforcing cords for belt and carcass. CONSTITUTION: A fiber having >=7.0 g/denier strength and long-period of small angle X-ray of <=160 Å obtained by high stress spinning of a polyethylene terephthalate polymer having <=1.5 wt.% diethylene glycol content, terminal carboxyl group content of <=15 equivalent/10<6> g polymer, preferably, <=10 equivalent/10<6> g polymer, including >=90 mole % polyethylene terephthalate units and having an intrinsic viscosity of >=0.9, is dipped and heat-treated. This dip cord is used for reinforcement of a belt and/or a carcass of a pneumatic radial tire having the carcass reinforced with a belt mounted on the inside of a tread part.
