Abstract

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 (Tg) according to DSC of −75 to −120° 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.
