The invention relates to a sulfur-crosslinkable rubber mixture, especially for the tread of pneumatic vehicle tyres, comprising at least the following constituents: - 10 to 90 phr (parts by weight, based on 100 parts by weight of total rubbers in the mixture) of at least one solid, solution-polymerized, functionalized butadiene rubber, wherein the functionalization enables interaction with a polar filler, - at least one further diene rubber, - at least one liquid modified diene polymer A having a weight-average molecular weight Mw by GPC of 500 to 50000 g/mol, preferably 2000 to 10000 g/mol, where the modification enables interaction with a polar filler and is present along the polymer backbone, and - 10 to 300 phr of at least one silica.
