The present invention relates to rubber mixtures comprising at least one rubber and to 800 parts by wt. of filler, based on 100 parts by wt. of rubber, wherein the rubber has been prepared by polymerization of diolefins and optionally further vinylaromatic monomers and introduction of hydroxyl and/or carboxyl groups, this rubber has a total content of 0.05 to 5 wt.% of bonded hydroxyl and/or carboxyl groups or salts thereof, and has a content of polymerized-in vinylaromatic monomers of 0 to 50 wt.% and a content of diolefins of 45 to 99.95 wt.%, the content of 1,2- bonded diolefins (vinyl content) being 0 to 80 wt.%, and 0.001 to 40 parts by wt. of a compound which is capable of crosslinking the rubber with the hydroxyl or carboxyl groups of the rubber, and optionally further rubbers, rubber auxiliaries and crosslinking agents. The rubber mixtures according to the invention and vulcanization products thereof are suitable for the production of highly reinforced shaped rubber articles, in particular tyres, which have a particularly high resistance to thermal and mechanical stresses, a high wet skidding resistance, low rolling resistance and high abrasion resistance.
