The invention relates to a sulfur-crosslinkable rubber mixture, in particular for rubber reinforcements and / or belt edge strips of pneumatic vehicle tires. The invention further relates to a pneumatic vehicle tire which has such a rubber mixture vulcanized with sulfur. The rubber mixture contains 50 to 95 phr (parts by weight, based on 100 parts by weight of the total rubbers in the mixture) natural rubber, 5 to 50 phr of a microdispersion of syndiotactic 1,2-polybutadiene in cis-1,4-polybutadiene, the microdispersion being 5 to 40% by weight of the syndiotactic 1,2-polybutadiene, 0 to 35 phr of at least one other diene rubber besides natural rubber and 45 to 100 phr of silica and / or carbon black. |
