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, containing 30 to 300 phr of at least one silicic acid, and containing 1 to 20 phf of at least one substance according to formula I) as a silane coupling agent I) (R1R2R3)Si-S4-Si(R3R2R1), wherein R1, R2, and R3 in the structure can be the same or different and can be selected from linear or branched alkoxy, cycloalkoxy, alkyl, cycloalkyl, or aryl gruops having 1 to 20 carbon atoms. |
