Embodiment Construction

[0030] figure 1 A partial section of a car tire is shown schematically and by way of example. The usual constituents of this tire include in particular: a tread 1, a belt structure 2 arranged radially inside the tread 1 and comprising a plurality of cord belt layers, and optionally a belt band, furthermore a radial carcass 3. The largely airtight inner liner 4, and the sidewalls (not shown), as well as the bead areas (with bead cores, core profiles, and possibly also reinforcing plies arranged in these bead areas ). The tread 1 is equipped, inter alia, with profiles (not shown) in a manner known per se.

[0031] The tread 1 extends across the width of the tire in the ground contact zone and ends in the shoulder zone 5 . In these shoulders, it is possible to provide a tread termination zone composed of sidewall compound.

[0032] Figure 2 to Figure 6 Each schematically shows an embodiment of the tread according to the invention. These examples are suitable for figure 1 ...

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.

Description

technical field [0001] The invention relates to a pneumatic tire for vehicles with a tread, wherein the tread has a tread section arranged radially on the outside, wherein the tread section has a strip of material approximately at the circumference direction, arranged helically with multiple turns, 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 consists of a first A rubber compound is formed and the second layer is formed of a second rubber compound different from the first rubber compound, and wherein the first layer and the second layer connect the radially outer surface of the tread segment to the tire on the radially inner surface of the face segment. The invention also relates to a method for producing a pneumatic tire for vehicles of this type. Background technique [0002] There are different requirements for the tread of pneumatic tires for vehicles...
