RUBBER COMPOSITION AND VEHICLE TYRE

The invention relates to a sulfur-crosslinkable rubber mixture, in particular for tire treads of vehicle tires, and a vehicle tire. The sulfur-crosslinkable rubber mixture contains: - 20 to 100 phr of at least one functionalized styrene-butadiene copolymer A, wherein the functionalized styrene-butadiene copolymer is functionalized per polymer chain at at least one chain end with an amino-group-containing alkoxysilyl group and at least one further alkoxysilyl group(s) and/or at least one further amino-group-containing alkoxysilyl group(s), and - 20 to 300 phr of at least one highly dispersible silica.
