FIELD: automotive industry; tyre industry.
SUBSTANCE: invention relates to design of radial-ply tyres for trucks. Proposed tyre casing contains tread, breaker, carcass, side strips and bead rings. Diameter of metal cord is from 0.87 to 0.97mm. Metal cord proper is made of metal threads of equal diameter, ratio of diameter of metal thread to diameter of metal cord being from 0.242 to 0.293. Ratio of pitch of metal cord in breaker to diameter of metal cord is from 1.85 to 2.076, and linear density of metal cord lies within 2.84 and 3.16 g/m. Ratio of thickness of each rubber-lined layer of metal cord in breaker to diameter of metal cord is from 1.62 to 1.85, and breaking strength of metal cord is not lower than 955±5N.
EFFECT: reduced materials usage, labour input and power consumption at production of tyres.
