The invention relates to a silane, to a rubber mixture comprising the silane and to a vehicle tire comprising the rubber mixture in at least one component. n The inventive silane has the following formula I) n (R 1 ) o Si—R 2 —X-A-Y-[A-Y-] m -A-S k -A-[-Y-A] m -Y-A-X—R 2 —Si(R 1 ) o ,n wherein, according to the invention, the silane has spacer groups between the respective silyl groups and the S k moiety which have at least two aromatic groups A and the linking units X and Y, wherein the groups X within a molecule may be identical or different from each other and are selected from the groups —HNC(═O)—, —C(═O)NH—, —C(═O)O—, —OC(═O)—, —OC(═O)NH—, —HNC(═O)O—, —R 3 NC(═O)NR 3 —, —R 3 NC(═NR 3 )NR 3 —, —R 3 NC(═S)NR 3 —, wherein at least one R 3 within each group X is a hydrogen atom; and wherein the groups Y within a molecule may be identical or different from each other and are selected from the groups —HNC(═O)—, —C(═O)NH—, —C(═O)O—, —OC(═O)—, —OC(═O)NH—, —HNC(═O)O—, —R 4 NC(═O)NR 4 —, —R 4 NC(═NR 4 )NR 4 —, —R 4 NC(═S)NR 4 —, wherein at least one R 4 within each group Y is a hydrogen atom. nn The inventive rubber mixture comprises at least one inventive silane. |
