ABSTRACT:
An organic fiber cord for rubber reinforcement satisfies relationships of S1.gtoreq.2.5, S2.ltoreq.1.8 and S2.ltoreq.S1-2.0 wherein S1 and S2 are dry heat shrinkage factors under particular conditions in order to improve the durability and dimensional stability of rubber articles without the degradation of other properties in the rubber article. When such an organic fiber cord is applied to a carcass ply of a pneumatic radial tire, the tire durability and uniformity are considerably improved.
