The invention relates to a rubber mixture, in particular for vehicle tires, which mixture is distinguished by improved rolling resistance behavior and improved wear properties, and to a vehicle tire. For this purpose, the rubber mixture contains at least the following components: − 5 to 100 phr of at least one polymer A as per the following formula I): I) F-(P-Y-P-S x ) z -P-Y-P-F, wherein S is a sulfur atom, P is an elastomeric polymer chain that was obtained by the anionic polymerization of at least one conjugated diene and optionally at least one vinyl aromatic compound in the presence of a diinitiator, Y is a dicarbanion group that is derived from the diinitiator, x is an integer greater than or equal to 1 independently for each S x group, on the condition that x is selected from the numbers 2, 3, and 4 for at least one S x group, z is an integer from 1 to 160, and each F is a terminal group selected from the group consisting of -H, -SH, -SOH, -SCl, -SSCl, -SO 2 H, and -SO 3 H independently of one another, and at least one filler. |
