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.
