Abstract: 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.

Abstract: Disclosed are pneumatic vehicle tires and methods of their production, the tires comprising a tread that has a tread segment arranged radially on the outside, and a material strip that is arranged helically in windings approximately in the circumferential direction, wherein, in the region of the tread segment, the material strip has at least two layers in the longitudinal direction of the material strip, wherein the first layer is formed from a first rubber compound and the second layer is formed from a second rubber compound, and wherein the layers connect the radially outer surface to the radially inner surface of the tread segment. The disclosed pneumatic vehicle tire has lower noise emissions and more uniform wear during driving and is improved in respect of at least one conflict of aims.
