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 rubber mixture contains: - at least one diene rubber and - at least one silica and - 3 to 15 phf of at least one blocked and/or unblocked mercaptosilane and - 1 to 40 phr of at least one liquid polybutadiene which is terminally organosilicon-modified and has a weight-average molecular weight Mw according to GPC of 500 to 12000 g/mol.
