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): ≤50 phr of a first rubber, the first rubber being a solution polymerized styrene-butadiene rubber (SSBR) comprising an alkoxysilane group and a primary amino group; ≥20 phr of a second rubber; and a coupling agent, a filler, and a resin, wherein the rubber composition comprises ≥15 phr of a third rubber; and ≥10 phr of a fourth rubber; and wherein the composition comprises ≥1 phr to ≤20 phr of at least two coupling agents wherein one of the coupling agents is or comprises a mercapto based silane and wherein the ratio of the mercapto based silane to the second coupling agent is in a range of ≥2:1 to ≤10:1.

Rubber composition for tyres with low rolling resistance and good winter properties

The present invention relates to a cross-linkable rubber composition, the cross-linkable rubber composition comprising a natural rubber (NR), a filler, and a resin. The resin is a terpolymer of ethylene, acrylic ester and maleic anhydride and is present in an amount ranging from ≥5 to ≤20 phr.
