Abstract: A cross-linkable rubber composition for a tyre tread, the cross-linkable rubber composition comprising, per hundred parts by weight of rubber (phr) a solution polymerized styrene-butadiene rubber (SSBR) comprising an alkoxysilane group and a primary amino group; ≥45 phr of at least one filler; and ≥1 phr of a resin; characterised in that the composition comprises ≥90 phr to ≤100 phr of the SSBR, wherein the SSBR has a styrene content of 20% to 35% and a vinyl content of 48% to 60% (as determined by nuclear magnetic resonance (NMR) spectroscopy) and a glass transition temperature Tg (determined by differential scanning calorimetry (DSC) according to ISO 22768) between −23 #C to −30 #C.

Abstract: The present invention relates to a cross-linkable rubber composition for body compounds of a tyre, the cross-linkable rubber composition comprising, based upon parts by weight per 100 parts by weight rubber (phr): ≥30 to ≤90 phr of a natural rubber or isoprene rubber or combination thereof, ≥10 to ≤25 phr of a syndiotactic 1, 2-polybutadiene, ≥3 to ≤10 phr of a resin, and a filler, wherein the ratio in phr (parts by weight per 100 parts by weight of rubber) of the syndiotactic 1, 2-polybutadiene to the resin is in the range of ≥1:1 to ≤7:1.
