The present invention relates to an alkoxysilyl group in which at least one of the polymers A or B is an epoxy group, a hydroxy group, a carboxy group, a silane-sulfide group, an amino group, a siloxane group, an organosilicon group, a phthalocyanine group, and an amino group. At least one high molecular weight, solution polymerized diene polymer A and at least one low molecular weight functionalized with at least one group selected from at the chain end and / or along the polymer chain and / or at the coupling center , Containing a rubber blend of solution polymerized polymer B, 30-300 phr of at least one silicic acid, and 1-20 phf of at least one blocked and / or unblocked mercaptosilane as silane coupling agent , Sulfur crosslinkable rubber mixture About. |
