A sulfur-crosslinkable rubber mixture for pneumatic tires is disclosed. The rubber mixture includes at least one diene rubber and 10 to 200 phr of at least one silica and 2 to 20 phf of at least one silane having the general empirical formula (I) [(R1)3Si—X]mSn(R2)2-m. The R1 radicals within a molecule may be the same or different and are alkoxy groups having 1 to 10 carbon atoms or cyclic dialkoxy groups having 2 to 10 carbon atoms or cycloalkoxy groups having 4 to 10 carbon atoms or phenoxy groups or halides, and where m assumes the value of 1 or 2 and where n is an integer from 1 to 8 and where R2 is a hydrogen atom or an acyl group having 1 to 20 carbon atoms and where X is an organic spacer group having 3 to 30 carbon atoms and containing at least one organic radical. The organic radical is a) an allyl group; b) a phenyl group which has linkages to the silicon atom of the silyl group (R1)3Si— and to a sulfur atom of the Sn group via an alkyl radical having 0 to 20 carbon atoms in the 1,2 positions relative to one another; c) a phenyl group which has linkages to the silicon atom of the silyl group (R1)3Si— and to a sulfur atom of the Sn group via an alkyl radical having 0 to 20 carbon atoms in the 1,3 positions relative to one another; d) a phenyl group which has linkages to the silicon atom of the silyl group (R1)3Si— and to a sulfur atom of the Sn group via an alkyl radical having 0 to 20 carbon atoms in the 1,4 positions relative to one another; or e) fused aromatic ring systems which have linkages to the silicon atom of the silyl group (R1)3Si— and to a sulfur atom of the Sn group via an alkyl radical having 0 to 20 carbon atoms.
