FIELD: tire industry; road vehicles. SUBSTANCE: radial-ply pneumatic tire has breaker belt with at least two working layers of metal no- stretch cord and two limit-stops, each being formed by at least one layer of metal cord orientated at angle up to 10 deg relative to peripheral direction. Limit-stops are located in two different zones at one and the other sides from equatorial plane in radial direction between carcass fittings and inner layer of breaker belt in radial direction. Two indicated limit-stops are connected in axial direction by additional fittings consisting of at least one layer of textile or metal cord orientated in peripheral direction and centered on equatorial plane, with tensile strength being equal; to maximum half the tensile strength of most extensible layer of limit-stops.
