A method of producing rubber compounds, in which the polymer base is composed partly of a first polymer material, which is either produced by emulsion polymerization or is natural rubber, and partly of a second polymer material produced by solution polymerization. The method includes a preliminary second polymer material treating step, in which the second polymer material, silica, a silane bonding agent, and at least one nucleophile agent are mixed with one another; a first mixing step, in which at least the first polymer material, silica, and a silane bonding agent are added to the compound resulting from the preliminary second polymer material treating step; and a second mixing step, in which stearic acid and a curing system are added to the compound being produced.
