The invention relates to a sulfur-crosslinkable rubber mixture, containing: a rubber blend of at least one high-molecular-weight, solution-polymerized diene polymer A and at least one low-molecular-weight, solution-polymerized polymer B, wherein at least one of the polymers A or B is functionalized at the chain end and/or along the polymer chain and/or in a coupling center with at least one group selected from epoxy groups, hydroxy groups, carboxy groups, silane-sulfide groups, amino groups, siloxane groups, organosilicon groups, phthalocyanine groups, and from alkoxysilyl groups containing amino groups, and as a filler, at least one silicic acid and/or at least one carbon black in an amount of 25 to 300 phr, wherein the ratio of carbon black to silicic acid in the mixture is 100:0 to 3:97. |
