A rubber compound, cross-linkable with sulfur, is described, containing: (a) at least one diene polymer or copolymer; (b) at least one finely divided, acid-activated layer silicate derived from a smectitic layer silicate as reinforcing filler; (c) at least one coupler with groups reactive relative to filler (b). The cross-linkable rubber compound can be produced according to a method comprising the following steps: (i) Mixing of the diene polymer or copolymer (a) and the reinforcing filler (b) with coupler (c) and/or optionally with a master batch mixture of filler (b) with coupler (c1) and optionally with additional ordinary additives, except for vulcanization chemicals, using ordinary mixing equipment at about 105 to 150° C.; (ii) Mixing of the vulcanization chemicals at a temperature of less than about 100° C. The object of the invention is also a rubber compound cross-linkable with sulfur that can be obtained from the rubber compound, cross-linkable with sulfur, by vulcanization at temperatures of more than about 100° C. Finally, molded articles, especially vehicle tires or parts thereof, rubber bearings, conveyor belts, hoses and sealing elements that are obtainable from the cross-linkable or cross-linked rubber compounds are objects of the invention.
