  "textContent": "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): 100 phr of a blend of a natural rubber (NR), a polybutadiene rubber (BR), and first and second solution polymerized styrene-butadiene rubbers (SSBR); a silica filler, a resin, and ≥ 1 phr to ≤ 20 phr of first and second coupling agents, wherein the first coupling agent is a mercaptosilane and the second coupling agent is selected from a disulfide silane, a tetrasulfide silane, or a combination thereof. The cross-linkable rubber composition further comprises: ≥ 10 phr to ≤ 40 phr of NR; ≥ 20 phr to ≤ 80 phr of BR; ≥ 10 phr to ≤ 50 phr of the first SSBR having a glass transition temperature Tg (measured by differential scanning calorimetry (DSC) according to ISO 22768) of ≥ -30°C to ≤ 0°C; ≥ 10 phr to ≤ 30 phr of the second SSBR having a glass transition temperature Tg (measured by differential scanning calorimetry (DSC) according to ISO 22768) of ≥ -120°C to ≤ -40°C; ≥ 60 phr to ≤ 130 phr of a first silica filler having a BET surface area in a range of ≥ 150 m2/g to ≤ 200 m2/g (according to ASTM D1993), and ≥ 10 phr to ≤ 100 phr of a second silica filler having a BET surface area in a range of ≥ 70 m2/g to ≤ 100 m2/g (according to ASTM D1993).",
