The invention relates to a sulfur-crosslinkable rubber mixture, in particular for rubber-coating reinforcements in elastomer products, especially in vehicle tires, or inner components of vehicle tires, as well as to a vehicle tire. The rubber mixture comprises a diene rubber, an adhesive system, 10 to 200 phr silica, and 2 to 20 phr of a silane of the formula [(R1)3Si—X]mSn(R2)2-m, where residues R1 are identical or different alkoxy groups, cyclic dialkoxy groups, cycloalkoxy groups, phenoxy groups, aryl groups, alkyl groups, alkenyl groups, aralkyl groups, or halides, and where X is a polar organic group containing urea, m represents the value 1 or 2, n is an integer between 1 and 8, and R2 is a hydrogen atom or an acyl group comprising 1 to 20 carbon atoms.
