The present invention relates to rubber mixtures with improved processing behavior and high filler activity, containing 1,4-butenediol and/or 1,4-butenediol polyether, as well as the use of the rubber mixtures for the production of vulcanizates, in particular for the production of highly reinforced, abrasion-resistant molded articles, and preferably for the production of tires that have a low rolling resistance and a high abrasion resistance.
