    A tire has an asymmetrical carcass comprising two plies of cords forming a network of quadrilateral meshes. The sides of the quadrilaterals form with the circumferential direction of the tire acute angles alpha and beta which are different and which vary as a function of the distance of the mesh from the axis of the tire. The angle alpha is larger than the angle beta and varies, between any two points located at different distances from the axis, more than does the angle beta . In manufacturing the tire by turning the edges of the two plies around bead wires on a building drum and then shaping the assembly into the form of a tire, at least one of the bead wires is permitted to rotate about the axis of the tire so that the meshes rotate about normals to the carcass.

    The invention relates to the tire industry, in particular to the designs of tires of pneumatic tires. A pneumatic tire is known, comprising a carcass consisting of two layers of filaments, varying depending on the distance from the axis of rotation of the tire, the angle of inclination and forming a system of cells, the opposite sides of which are predominantly parallel to l. However, tires - pneumatic tires - have a short service life. The aim of the invention is to increase the life span of a pneumatic tire. For this, in the proposed tire, the sides of the cells belonging to different layers form unequal angles with the circumferential direction, while between any two points lying at different distances from the axis, the values of the larger angle are larger than the change in the values of the smaller angle . In addition, the sides of the cells belonging to the same layer of filaments, MOfyT have the same length. . The indicated angles of inclination of the filaments of different layers —in the onboard zone may be in the same kps1, a strand bounded by radial and circumferential directions; the sum of the angles of inclination of the filaments in the side zone relative to the circumferential direction may be less in the zones of the closest and most distant tire tires from the axis. They may have the same area, and the opposite sides of the cells may be at the same distance from one another; a layer of filaments having a different angle of inclination may be located above a layer of filaments having a greater angle of inclination, separated from them by a layer of rubber with elasticity 200-500 100% elongation and its filaments are more elastic than the filaments of the inner layer.
