Embodiment Construction

[0021] figure 1 and figure 2 A commercial vehicle pneumatic tire of radial construction is shown having two side walls 2 extending in the radial direction R of the vehicle pneumatic tire and a crown region (top region) formed axially therebetween 3. At the end of their extension directed inwards in the radial direction, the side walls are each formed with a bead region 1 in which a stretch-resistant, zugfester in the circumferential direction U is formed. A bead core 4 of known type extending on the circumference of the tyre. The bead core 4 is formed in a known manner from a coil of wire embedded in rubber extending in the circumferential direction U of the vehicle pneumatic tire. On the bead core 4 , a horn (core shoe) 6 with a triangular cross-section is formed in a conventional manner from hard rubber material. The vehicle pneumatic tire is formed to have a carcass 5 passing outwardly in the radial direction R of the vehicle pneumatic tire from the bead core 4 formed...

Abstract

Vehicle tyres for commercial vehicles, comprising a carcass (5), a belt (9) configured radially outside the carcass (5) and a profiled tread (10) configured radially outside the belt (9) on the belt (9), wherein the belt (9) is formed from at least four belt plies (13, 14, 15, 17) arranged on each other radially from the inside to radially on the outside, wherein the reinforcements (23) of the first belt ply (13) enclose in the alignment thereof an angle of 10 DEG - 45 DEG with respect to the circumferential direction and the reinforcements (25) of the third belt ply (15) in alignment thereof enclose an angle of 10 DEG - 45 DEG with respect to the circumferential direction, wherein as viewed in the circumferential direction (U) of the vehicle tyre the reinforcements (23) of the first belt ply (13) comprise an opposite axial direction of inclination with respect to the reinforcements (25) of the third belt ply (15), and wherein the reinforcements (24) of the second belt ply (14) in the alignment thereof enclose an angle of 0 DEG- 5 DEG with respect to the circumferential direction, characterized in that the reinforcements (27) of the fourth belt ply (17) in the alignment thereof enclose an angle of 50 DEG - 52 DEG with respect to the circumferential direction.

Description

technical field [0001] The present invention relates to a vehicle pneumatic tire for commercial vehicles, the vehicle pneumatic tire having a carcass, a cord belt formed radially outside the carcass, and a cord belt formed radially outside the cord belt. A profiled tread on a cord band, wherein the cord band is formed of at least four cord band layers arranged one above the other from the radially inner towards the radially outer, wherein the innermost arranged in the radial direction R The first cord belt layer is formed to have a reinforcing fabric embedded in rubber in parallel, and the second cord belt layer arranged on the first cord belt layer is formed to have a reinforcing fabric embedded in rubber in parallel. The third cord tape layer arranged on the second cord tape layer is formed to have a reinforcing fabric embedded in rubber in parallel and the fourth cord tape layer arranged on the third cord tape layer is formed to have a rubber embedded in parallel. The rein...
