The invention relates to a rubber mixture, in particular for vehicle tires, to a vulcanizate of the rubber mixture, and to a vehicle tire. For this purpose, the rubber mixture contains at least the following components: - at least one filler and - 10 to 100 phr of at least one polymer A according to the following formula (I), in which S is a sulfur atom and P is a polymer chain that can be obtained by the anionic polymerization of at least one conjugated diene and optionally one or more vinyl aromatic compounds and is optionally chain-end modified, R1 is independently selected from C1-C11-alkyl, C6-C11-aryl, C7-C11-aralkyl, and C2-C11-dialkyl ether, preferably C1-C11-alkyl, and particularly preferably C1-C8-alkyl, R2 is independently selected from H, C1-C11-alkyl, C6-C11-aryl, C7-C11-aralkyl, C2-C11-dialkyl ether, and -SiR3R4R5, wherein R3, R4 and R5 are independently selected from H, C1-C16-alkyl, C6-C16-aryl, and C7-C16-aralkyl, and R2 is preferably independently selected from H and -SiR3R4R5, wherein R3, R4 and R5 are independently selected from H, C1-C16-alkyl, C6-C16-aryl and C7-C16-aralkyl, and n is a whole number, selected from 1 to 200, preferably 1 to 100, particularly preferably 1 to 50, and the group(s) -S-R1S-R2 are bonded to the backbone of the polymer chain P.
