Abstract: The invention relates to a sulfur-crosslinkable rubber mixture, to a vulcanizate and to a vehicle tire. The sulfur-crosslinkable rubber mixture contains at least the following constituents: 50 to 100 phr of at least one polyisoprene selected from the group consisting of natural and synthetic polyisoprene and 5 to 500 phr of at least one silica and at least one silane B having the general empirical formula I) (R1)oSi—R2—Sn—R2—Si(R1)o where the R2 radicals may independently be the same or different and are unbranched alkylene groups having 6 to 20 carbon atoms, preferably 6 to 10 carbon atoms, and where n is an integer from 2 to 10.

Abstract: A sulfur-crosslinkable rubber mixture, a vulcanizate thereof, and a vehicle tire. The sulfur-crosslinkable rubber mixture contains at least the following constituents: a) 1 to 30 phf of at least one silane A selected from the silanes having the general empirical formulae A-I) and A-XI): A-I) (R1)oSi—R20—(S—R30)m—Sx—(R30—S)m—R20—Si(R1)o; A-XI) (R1)oSi—R2—(S—R3)q—S—X; and b) 0.5 to 30 phf of at least one silane B selected from the silanes having the general empirical formulae B-I), B-01) and B-02): B-I) (R1)oSi—R4—(S—R5)u—S—R4—Si(R1)o; B-01) (R1)oSi—R10—Si(R1)o; B-02) (R1)oSi—R9; and c) 12 to 300 phr of silicon dioxide having a CTAB surface area to ASTM D 3765 of 190 to 300 m2/g; and d) at least one diene rubber, where x is an integer from 2 to 10; and q is 1 or 2 or 3; and u is 1 or 2 or 3; and X is a hydrogen atom or a —C(?O)—R8 group where R8 is selected from hydrogen, C1-C20-alkyl groups, C6-C20-aryl groups, C2-C20-alkenyl groups and C7-C20-aralkyl groups.
