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 silica acid; and 1 to 30 phf of at least one silane A having the general empirical formula A-I) A-I)(R1)oSi-R2-(S-R3)q-S-X; and 0.5 to 30 phf of at least one silane B having the general empirical formula B-I) B-I) (R1)oSi-R2-(S-R3)u-S-R2-Si(R1)o wherein q =1, 2 or 3; and u = 1, 2 or 3; and X is a hydrogen atom or a –C(=O)-R8 group, wherein R8 is selected from hydrogen, C1-C20 alkyl groups, preferably C1-C17, C6-C20- aryl groups, preferably phenyl, C2-C20-alkenyl groups and C7-C20-aralkyl groups. |
