The invention relates to the branch of pneumatic large-dimension and super-large tires of diagonal design. A body of tires is made from a rubberized textile cord. The object of the invention consists in the development of large-dimension and super-large tires with increased speed characteristics due to the development of textile cords of increased tensile strength without considerable increase of the thread diameter. The technical problem is solved due to the fact that the tire casing of diagonal design, which contains a body from textile cord and a board from wires of bead rings, in accordance with the disclosed invention includes not less than four bead rings, the body is made from the textile cord, which has threads with following structure: 144 tex х1 х3, 188 (187) tex х1 х3 or 188 (187) tex х2 х2, or 210 tex х1 х3, or 210 tex х2 х2 or 280 tex х1 х3 with the number of torsions within the limits of 180-240 per linear meter, which ensures the ratio of bead rings to the tension of body within the limits of values 0.9-1.3. The technical result consists in increase of the tensile strength of the material of cord without considerable increase of the thread diameter; in increase of strength of the connection cord-body-rubber; in development of the designs of tires with increased indices of load and category of speed; in increase or not worsening of initial indices of the tires in operation. |
