Rubber vulcanizates having a reduced heat evolution when subjected to dynamic deformation, prepared from vulcanizable rubber mixtures containing at least one type of rubber, a reinforcing resin system based on curable phenolic resins and other customary constituents, the vulcanizable rubber mixtures having been prepared from at least two rubber mixtures of different compositions. A process for their preparation by preparing in each case at least two different rubber mixtures differing from one another in their content of rubber, filler, oil, reinforcing resin system and, if appropriate, thermoplastic copolymer, by mixing the constituents thereof, then mixing the resulting mixtures with one another and vulcanizing the resulting final mixture. The use of the vulcanizable rubber final mixtures is for the production of mechanical rubber goods and tires.
