Abstract
A pneumatic radial tire is disclosed. This tire is reinforced with steel cords, each of which has such a flat or elliptic section that two or three strands, each strand being produced by twisting plural filaments, are arranged in parallel with each other so as to make the twisting directions of the adjoining strands opposite to each other to form a core and plural filaments are twisted around the core and wrapped with a spiral filament.
