The invention relates to a pneumatic vehicle tire, which has a tread (1), which has a tread segment (6) that is arranged radially outside, said tread segment having a material strip (7) that is arranged helically in windings approximately in the circumferential direction, wherein the material strip (7) in the region of the tread segment (6) has at least two layers (8, 9) in the longitudinal direction of the material strip, wherein the first layer (8) is formed of a first rubber mixture and the second layer (9) is formed of a second rubber mixture and wherein the layers (8, 9) connect the radially outer surface (10) to the radially inner surface (11) of the tread segment (6). The problem addressed by the invention is the creation of a pneumatic vehicle tire that has advantageous snow driving behavior and, at the same time, improved properties on a dry roadway. In addition, the tire should be simple to produce. This problem is solved in that the second rubber mixture has a Shore A hardness that is greater than the Shore A hardness of the first rubber mixture by at least 2 Shore A, preferably by 4 Shore A to 12 Shore A, and in that the first and the second rubber mixtures have approximately the same stress value. The invention further relates to a method for producing such a pneumatic vehicle tire.
