Abstract

The invention relates to a silane, to a rubber mixture containing the silane and to a vehicle tire comprising 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,  I) wherein according to the invention it has a spacer group between the silyl group and the S-G moiety, wherein the spacer group has an aromatic group A and at least one further aromatic group and/or an alkylene group and also the linking units X and Y, wherein the 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—, wherein at least one R3 within the group X is a hydrogen atom, and wherein 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—, wherein at least one R4 within each group Y is a hydrogen atom, and wherein the radicals R7 are selected from aromatic groups A and alkylene radicals having 1 to 20 carbon atoms, which may have cyclic, branched and/or aliphatically unsaturated groups; and wherein G is a hydrogen atom or a —C(═O)—R…
