The invention relates to a rubber blend, to a sulfur-crosslinkable rubber mixture comprising the rubber blend and to a vehicle tire comprising such a rubber mixture. The rubber blend comprises

Rubber blend, sulfur-crosslinkable rubber mixture, and vehicle tire

The invention relates to a pneumatic vehicle tire, which has a tread (), which has a tread segment () that is arranged radially outside, said tread segment having a material strip () that is arranged helically in windings approximately in the circumferential direction, wherein the material strip () in the region of the tread segment () has at least two layers () in the longitudinal direction of the material strip, wherein the first layer () is formed of a first rubber mixture and the second layer () is formed of a second rubber mixture and wherein the layers () connect the radially outer surface () to the radially inner surface () of the tread segment (). 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.

Pneumatic vehicle tire having a tread

A sulfur-crosslinkable rubber mixture comprising at least the following constituents:

Sulfur-crosslinkable rubber mixture, vulcanizate of the rubber mixture, and vehicle tire

The invention relates to a sulfur-crosslinkable rubber mixture comprising

The invention relates to a rubber blend, to a sulfur-crosslinkable rubber mixture comprising the rubber blend and to a vehicle tire comprising such a rubber mixture. The rubber blend comprises at least one solution-polymerized diene polymer A of high molecular weight and at least one solution-polymerized polymer B of low molecular weight, wherein at least one of polymers A and B has been functionalized at the chain end and/or along the polymer chain and/or at a coupling site with at least one group selected from epoxy groups, hydroxyl groups, carboxyl groups, silane sulfide groups, amino groups, siloxane groups, organosilicon groups, phthalocyanine groups and amino group-containing alkoxysilyl groups and wherein the rubber blend includes 35 to 100 phr (based on the at least one solution-polymerized diene polymer A of high molecular weight), preferably 35 to 70 phr, of the at least one solution-polymerized polymer B of low molecular weight.

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.

Disclosed are sulfur-crosslinkable rubber mixtures that can be incorporated into treads of vehicle tires, and vehicle tires comprising the disclosed sulfur-crosslinkable rubber mixtures. The rubber mixtures comprise: at least one diene rubber, at least one silica, at least one hydrocarbon resin, and 1 to 40 phr of at least one liquid polybutadiene having terminal organosilicon modification and having a weight-average molecular weight Mw by GPC of 500 to 12 000 g/mol.

Rubber mixture and vehicle tires

A sulfur-crosslinkable rubber mixture, in particular for pneumatic vehicle tires, straps, belts, and hoses, is disclosed which exhibits, among other things, improved rolling resistance behavior. The rubber mixture contains at least the following constituents: 5 to 95 phr of at least one styrene-butadiene rubber, which is functionalized with phthalocyanine groups and/or hydroxy groups and/or epoxy groups and/or silane-sulfide groups and the styrene content of which is 0 to 12 wt % and which has a glass transition temperature (T) according to DSC of &#x2212;75 to &#x2212;120&#xb0; C. in the unvulcanized state, 5 to 95 phr of at least one further rubber, and 20 to 300 phr of at least one silica.

Sulfur-crosslinkable rubber mixture

A rubber blend, particularly for pneumatic vehicle tires, harnesses, straps and hoses. The rubber blend includes at least one rubber blend A of a solid styrene-butadiene rubber with an average molecular weight Mof 100,000 to 5,000,000 g/mol and a liquid butadiene rubber with an average molecular weight Mof 500 to 9000 g/mol, wherein the styrene-butadiene rubber is solution-polymerized or emulsion-polymerized, as well as 30 to 300 phr of at least one silicic acid and further blend components.
