The invention pertains to a sulfur cross-linkable unvulcanized rubber mixture for the manufacture of treads, in particular for winter tires. The rubber mixture contains polyisoprene, polybutadiene and styrene-butadiene copolymer as well as further fillers and additives. In order to prepare vehicle pneumatic tires which exhibit excellent traction on ice and snow while at least maintaining their wet-gripping ability, the rubber mixture preferably contains, relative to 100 parts of total rubber, 20-100 parts by weight cis-1,4 polyisoprene; 0-65 parts by weight polybutadiene with a cis content of greater than about 90 mole %; and 0-65 parts by weight solution-polymerized styrene-butadiene copolymer; as well as 65-120 parts by weight silicic acid.
