FIELD: transport engineering.
SUBSTANCE: invention relates to pneumatic tyre with radial carcass reinforcement over which ridge reinforcement consisting of at least two working layers of ridge formed by metal reinforcement members is arranged in radial direction. Said reinforcement members intersect from one layer to the other forming angles of 10 to 35° with circumferential direction. Ridge reinforcement includes at least one additional reinforcement formed by metal reinforcement members orientated in circumferential direction. Additional reinforcement consists of at least two layers of metal members of small diameter not exceeding 0.6 mm. Metal reinforcement members of additional reinforcement are assemblies, type 1 x n where n is from 2 to 5, made of steel featuring high breaking strength SHT, and diameter of threads is within 12/100 and 30/100.
EFFECT: increased strength and wear resistance of tyres.
