The present invention relates to vulcanisable rubber mixtures containing at least the following components: I) 100 pbw of an oil-free rubber matrix consisting of a) 15-79 pbw, preferably 20-70 pbw of at least one solution SBR (L-SBR) (oil-free) with a glass transition temperature (Tg(L-SBR)) between -70°C and -10°C, b) 20-75 pbw, preferably 25-70 pbw of at least one 1,4-cis-polybutadiene (BR) (oil-free) with a glass transition temperature (Tg(BR)) between -95°C and -115°C, c) 1-37.5 pbw, preferably 5-35 pbw of natural rubber (NR) (oil-free) and/or at least one synthetically produced polyisoprene (IR) with a glass transition temperature (Tg(NR)) between -50°C and -75°C relative to the oil-free natural rubber (NR) or the oil-free synthetically produced polyisoprene (IR); II) at least one polybutadiene-based microgel that contains hydroxyl groups; III) at least one oxide filler that contains hydroxyl groups; IV) at least one polysulphide-containing alkoxysilane; V) at least one vulcanisation agent; VI) optionally at least one rubber additive. |
