The invention relates to a rubber blend, to a sulfur-crosslinkable rubber mixture containing the rubber blend, and to a vehicle tire containing such a rubber mixture. The rubber blend contains: 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, amino groups, siloxane groups, organosilicon groups, phthalocyanine groups, and from alkoxysilyl groups containing amino groups. |
