Abstract: 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. The cross-linkable rubber composition comprises, per hundred parts by weight of rubber (phr): ≥10 phr to ≤20 phr of a natural rubber or an isoprene rubber or a combination thereof; a filler; a resin, and first and second coupling agents, wherein the first coupling agent is a mercaptosilane and the second coupling agent is a silane selected from a disulfide silane, a tetrasulfide silane, or a combination thereof, wherein the rubber composition comprises ≥80 phr to ≤90 phr of a solution polymerized styrene-butadiene rubber (SSBR) comprising an alkoxysilane group and a primary amino group, and wherein the weight by weight ratio of the mercaptosilane to the silane is in a range of ≥2:1 to ≤4:1.
