The invention relates to a sulfur-crosslinkable rubber mixture comprisinga rubber blend composed of at least one solution-polymerized diene polymer A of high molecular weight and at least one solution-polymerized polymer B of low molecular weight, wherein at least one of polymers A and B has been functionalized at the chain end and/or along the polymer chain and/or at a coupling site with at least one group selected from epoxy groups, hydroxyl groups, carboxyl groups, silane sulfide groups, amino groups, siloxane groups, organosilicon groups, phthalocyanine groups and amino group-containing alkoxysilyl groups,30 to 300 phr of at least one silica and1 to 20 phf of at least one blocked and/or unblocked mercaptosilane as silane coupling agent. |
