ABSTRACT:
Rubber mixtures vulcanisable with sulphur are proposed which lead to tires with a good rolling resistance and driving behavior on wet roads without the other driving characteristics deteriorating. The rubber mixtures contain a copolymer of conjugated diene and vinyl aromatic compound manufactured by emulsion polymerisation, polyisoprene, polybutadiene, silica, carbon black in a specific range of quantities and also customary additives and a vulcanisation system. A further embodiment additionally contains copolymer manufactured by solution polymerisation in specific quantity ranges, and in this embodiment the polyisoprene is an optional component.
