FIELD: tires production.
SUBSTANCE: the invention is pertinent to the motor vehicles tires industry and may be used at production of tires for transportation vehicles. The method provides, that in process of the tires production first they form a carcass structure for the tire outer side, put a breaker band on external peripheral surface of a tire, put a tire tread band on a circle of the breaker band and together with it put the tire side members on opposite sides of the tire carcass structure. At forming the tire carcass structure the preparation of its sections made in the form of bands is exercised. Each of which contains the longitudinal and parallel threadlike elements coated, at least by one layer of a raw elastomeric material. The first, second, third and fourth sets of sections are laid down in the form of bands, each of which passes according to the U-shaped configuration around the contour of a cross-section of the toroidal basis. Then the first and second ring-shaped reinforcing structures are superimposed on the ends of the corresponding sections having the form of bands. The tire contains a carcass structure, a breaker strip, a tire-tread band and side-frames. The carcass structure contains the first and the second layers of the skeleton formed from the sections having the U-shaped configuration, two threadlike elements, covered with a layer of the elastomeric material, and a pair of the ring-shaped reinforcing structures. The first layer of the carcass contains the first and second sets of sections in the form of bands. The second layer of the carcass contains the third and fourth sets of sections made in the form of bands. Each ring-shaped structure contains the first and the second basic parts. The method allows to design low-profile tires with strong side members, and so produced tire has the strong tire beads and side members sustaining the high twisting moments transferred by the tire.
EFFECT: the method allows to design low-profile tires with strong side members sustaining the high twisting moments transferred by the tire.
