Abstract

The invention relates to a pneumatic vehicle tire, comprising a carcass (5), a belt (9), and a profiled tread (10), wherein the belt (9) is composed of at least three belt plies (13, 14, 15) arranged one on top of the other from the radial inside to the radial outside, wherein the radially inner (13) and the radially outer (15) working plies have opposite axial inclination directions of the reinforcements (25), and wherein a belt ply (14) arranged between said two working plies (13, 15) has reinforcements (24), the orientations of which include an angle β of 0°≦β≦5° with respect to the circumferential direction U, and wherein the orientations of the reinforcements (23, 25) of one of the two working plies (13, 15) include an angle α of 10°≦α<45° with respect to the circumferential direction U, and the orientations of the reinforcements (25, 23) of the other of the two working plies (15, 13) include an angle γ of 45°≦γ≦90° with respect to the circumferential direction U.
