摘要

PURPOSE: A lightweight environment-friendly radial tire for a vehicle is provided to reduce rotational resistance and to improve fuel efficiency.;CONSTITUTION: A lightweight environment-friendly radial tire for a vehicle is formed by braiding a high-strength textile cord such as aramid. In case of a bead wire, an aramid cord of a conditioned size of 2,000 deniers or greater is applied to the bead wire and a belt portion of a tire and replaced.;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Roll a textile cord; (BB) Slit the rolled material to be thin; (CC) Braid the slit rolled material into a cylindrical shape; (DD) Cut the braided material in a cylindrical shape amounting to the size of a tire to fit the width of the tire; (EE) Manufacture the tire with the cut braided material as a belt layer
