FIELD: tire industry. SUBSTANCE: invention relates to radial-ply tires whose breaker is reinforced by rubberized cloth made of metal brass- plated rectangular section threads. Said thread is made of soft ductile steel with ultimate rupture strength σu within 125 and 175 kgf/sq. mm and ratio of mass of breaker reinforcement material, with no account of rubber mass in breaker, to mass of tire is 8.2-25%. Invention makes it possible to create radial-ply tire containing rubberized cloth in breaker made of brass- plated rectangular sections threads with ratio of thickness to width from 0.2 to 0.6 and combination of said cloth with rubberized polyamide cord featuring high manufacturability of reinforcement material. EFFECT: increased wear resistance and tire run. 1 tbl, 1 dwg
