Zusammenfassung:The invention relates to a sulfur-crosslinkable rubber mixture, the vulcanizate thereof, and a vehicle tyre. The sulfur-crosslinkable rubber mixture contains at least the following constituents:- at least one diene rubber; and 10 to 300 phr of at least one silicic acid: and 1 to 30 phf of at least one silane A having a general empirical formula A-I) and/or A-XI). A-I): (R1)oSi-R2-(S-R3)q-Sx-(R3-S)q-R2-Si(R1)o; A-XI): (R1)oSi-R2-(S-R3)s-S-X; and 0.5 to 30 phf of at least one silane B having a general empirical formula B-I): B-I): (R1)oSi-R4-Si(R1)o, wherein x is a whole number from 2 to 10, q is equal to 0, 1, 2 or 3, and s is equal to 1, 2 or 3 and X is a hydrogen atom or -C(=O)-R8 group, wherein R8 is selected from hydrogen, C1-C20-alkyl groups, C6-C20-aryl groups, C2-C20-alkenyl groups and C7-C20-aralkyl groups.
