The invention relates to a silane, a rubber mixture containing the silane, and a vehicle tire having the rubber mixture in at least one component. The silane according to the invention has the following formula (I) (R1)oSi-R2-X-A-Y-[R7-Y-]m-R7-S-G, in which according to the invention the formula has a spacer group between the silyl group and the S-G grouping and the spacer group has an aromatic group A, at least one additional aromatic group and/or an alkylene group, and the linking units X and Y, wherein group X is selected from the groups -HNC(=O)-, -C(=O)NH-, -C(=O)O-, -OC(=O)-, -OC(=O)NH-,-HNC(=O)O-, -R3NC(=O)NR3-, -R3NC(=NR3)NR3-, -R3NC(=S)NR3-, and at least one R3 within the group X is a hydrogen atom; the groups Y are selected from the groups -HNC(=O)-, -C(=O)NH-, -C(=O)O-, -OC(=O)-, -OC(=O)NH-, -HNC(=O)O-, -R4NC(=O)NR4-, -R4NC(=NR4)NR4-, -R4NC(=S)NR4-, and at least one R4 within each group Y is a hydrogen atom; the groups R7 are selected from aromatic groups A and alkylene groups with 1 to 20 carbon atoms which can have cyclically, branched, and/or aliphatically unsaturated groups; group G is a hydrogen atom or a -C(=O)-R8 group or a -SiR8 3 group, and R8 is selected fromlinear, branched, and cyclical C1-C20 alkyl groups, C6-C20 aryl groups, C2-C20 alkenyl groups, and C7-C20 aralkyl groups; and m can take on the values 0 to 4. The rubber mixture according to the invention contains at least one silane according to the invention.
