摘要:
The invention relates to a sulfur-crosslinkable rubber mixture, in particular for the base of treads of the cap-base type of vehicle tires, and to a vehicle tire. Said rubber mixture contains: - at least one diene rubber and - 15 to 55 phr of at least one filler and - at least one hydrocarbon resin which is composed of 25 to 100% by weight of aromatic monomers, and has a softening point according to ASTM E 28 (ring and ball) of 70 to 130°C, and - 0 phr of further plasticizers, i.e. the sulfur-crosslinkable rubber mixture is free of further plasticizers.

The invention relates to a sulphur-crosslinkable rubber mixture, especially for treads of motor-vehicle tyres, and to a motor vehicle tyre. The rubber mixture comprises at least the following constituents: 40 to 100 phr of at least one natural and/or synthetic polyisoprene and 15 phr or more of at least one hydrocarbon resin formed to an extent of 50% to 100% by weight from aliphatic C 5 monomers and to an extent of 0% to 50% by weight from further monomers, where the hydrocarbon resin of the formula I) has a Q of 0.015 [°C-mol/g] to 0.050 [°C-mol/g]: I) Q = softening point [°C]/centrifuge average Mz [g/mol].

The invention relates to a sulphur-cross-linkable rubber blend, in particular for the treads of vehicle tyres, and to a vehicle tyre. The rubber blend contains at least the following constituents: 60 to 100 phr of at least one butadiene rubber and 51 phr or more of at least one hydrocarbon resin which is composed of 30 to 100 % by weight of aromatic monomers. The vehicle tyre contains the rubber blend at least in the tread.
