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 tire and a tire. A cross-linkable rubber composition comprises, per hundred parts by weight of rubber (phr): 100 phr of a diene-based elastomer component with an average molecular weight Mn in a range of ≥100000 to ≤5000000 g/mol and a homopolymer of polybutadiene, wherein the homopolymer of polybutadiene has an average molecular weight Mn in a range of ≥10000 to ≤45000 g/mol and a glass transition temperature Tg in a range of ≥−110° C. to ≤−60° C.
