FIELD: automotive industry; tires for heavy vehicles.
SUBSTANCE: each bead is strengthened by means of at least two additional members, namely, at least one first member formed by radial strengthening elements and at least one second member formed by metal strengthening elements forming angle between zero and 45o with circumferential direction. First member is formed by at least one layer wound around bead ring inside said carcass member to form two legs so that leg inner in axial direction of section between lower, in radial direction, end on its upper, in radial direction, edge parallel to meridional profile of carcass member and point of its contact with bead ring has trajectory passing over "shortest" way.
EFFECT: increased reliability and strength of tire.
