Rubber composition for tyres with low rolling resistance and good winter properties The present invention relates to a cross-linkable rubber composition, a cross-linked rubber composition obtained by cross-linking such a rubber composition, a method of preparing a tyre and a tyre. In a cross-linkable rubber composition, the cross-linkable rubber composition comprises, per hundred parts by weight of rubber (phr): ≥91 to ≤99 phr of natural rubber or isoprene rubber or combination thereof, a syndiotactic 1,2 polybutadiene, and ≥1 to ≤100 phr of a filler comprising carbon black, wherein the ratio of the syndiotactic 1,2 polybutadiene to the carbon black is in the range of 1:8 to 1:3 and in that the ratio of the syndiotactic 1,2 polybutadiene to the carbon black is in the range of ≥1:8 to ≤1:3.
