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 contains at least the following components: —at least one diene rubber; —at least one adhesive system; —10 to 200 phr of at least one silicic acid; and —2 to 20 phf of at least one silane of the general empirical formula I) [(R1)3Si-X]mSn(R2)2-m, where the residues R1 can be identical or different within a molecule and are alkoxy groups comprising 1 to 10 carbon atoms, cyclic d1 alkoxy groups comprising 2 to 10 carbon atoms, cycloalkoxy groups comprising 4 to 10 carbon atoms, phenoxy groups or aryl groups comprising 6 to 20 carbon atoms, alkyl groups comprising 1 to 10 carbon atoms, alkenyl groups comprising 2 to 20 carbon atoms, aralkyl groups comprising 7 to 20 carbon atoms, 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.
