    A tire with a radial carcass reinforcement and a tread reinforcement formed of at least three plies of cables is improved due to the fact that the tread reinforcement is formed of two plies of cables having a very low elongation and forming angles of 50 DEG -70 DEG with the longitudinal direction of the tire and of two plies of elastic cables forming angles of 5 DEG -15 DEG with the longitudinal direction of the tire.

    industries, in particular, to designs of pneumatic tires. A known pneumatic tire for heavy vehicles of all-terrain vehicles, comprising beads with bead rings, sidewalls, a tread, a carcass of at least one layer of radially arranged cord threads attached to at least one bead of each on each side, and a breaker radially outside the skeleton and formed from at least four layers of cord threads parallel to each layer and intersecting in adjacent layers, while the elastic threads of two of these layers are at an angle respect to the longitudinal direction and at least one of them but located radial outside of the other layers of the belt 1. However, the known structure has an insufficiently high service life. The purpose of the invention is to increase the service life by reducing the stresses simultaneously in the shoulder areas of the carcass and in the edge zones of the breaker and the sensitivity of the shoulder areas to cuts and punctures. This goal is achieved by the fact that, in a pneumatic tire, for heavy-duty off-road vehicles, containing flanges with bead rings, sidewalls, a tread, a carcass of at least one layer of radially located cords attached to at least one bead ring in each board and breaker located radially outside the frame and formed from at least four layers of yarn cord parallel in each layer and intersecting in adjacent layers, with j3TOM elastic strands of two of these layers are located At an angle of 5–15 relative to the longitudinal direction, and at least one of the HIs is located radially outside the rest of the belt, in the meridian section, the curvature of the framework in the equatorial zone is less than the curvature of the framework in the shoulder areas, where it is maximum, and the width of the two layers of elastic filaments the cord is 0.6-0.8 tread width, the relative elongation of the yarns of these layers is more than 0.5% with a force equal to two layers greater than the width of the tread, the relative elongation of the yarns of these layers is less than 0.2 with a force equal to 10% breaking strength and, and they are located at an angle of 55-60 relative to the longitudinal direction. In addition, the cords of the two other layers are made of steel with a twist pitch exceeding 12 times the diameter of the thread. The edges of the two other layers are located in the shoulder areas at a radial distance from the intersection point of the carcass with an equatorial plane smaller than 0.4 of the tire profile height, while the ratio of the height to width is at least equal to O, b5. One of the two other layers is located radially inside the two layers of elastic breaker threads. The threads of two layers of elastic threads must be at an angle of 8-12 relative to the longitudinal direction. Two layers of elastic cords are radially outside relative to other layers of the belt. FIG. 1 shows a pneumatic tire, an embodiment, a cross section; in Fig.2 - layers breiKepa and tire carcass; fig. 3 is a pneumatic tire, another embodiment. The pneumatic tire 1 contains beads 2 with side rings 3, sidewalls k, protector 5, a skeleton of one layer 6 radially arranged filaments 7 of the cord attached to the side rings 3f breaker 8 of four layers 9-12 filaments of 13-16 cords, respectively, located and each layer is parallel to each other and intersecting .c in adjacent layers. The elastic yarns 7 and 16 of layers 9 and 12 are located under the angle of 5-15, preferably 8-12 relative to the longitudinal direction. One of them (the 12D layer is located radially outside the rest of the breaker layers. In the meridian section, the curvature of the carcass layer 6 in the equatorial zone 17 is less than the curvature in the shoulder zones 18 where it is maximum. The width of the LI and L layers 9 and 12 is equal to 0.6 -0.8 width L of the tread 5. The relative elongation of the threads 7 and 16 of these layers.more than 0.5% at
    effort equal to 10 breaking strength. The widths L and L4 of layers 10 and 11 are greater than the width L of the tread 5. The relative elongation of the filaments I and 15 of these layers is less than 0.2% with force,
    equal to 10% of the rupture. They are located at an angle of 55-60 relative to the longitudinal direction.
    The edges of layers 10 and 11 can be located in the shoulder areas 18 at a distance h along the radius from the intersection point of layer 6 with the equatorial plane 19f less than 0.4 height H and tire profile 1, while the ratio of the height K1 of the profile to the width of the B, at least equal to 0.65.
    In one embodiment, one of the oil lines 10 and 11 may be located radially inside two layers 9 and 12 (Fig. 1).
    Layers 9 and 12 can be located radially outside with respect to layers 10 and 11 (Fig. 3).
    The proposed design of a pneumatic tire reduces stress in the shoulder areas of the carcass and edge zones of the breaker, reducing the sensitivity of the shoulder areas of the tire to cuts and punctures, thereby increasing the service life of the tire.
