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): ≥ 1 phr to ≤ 100 phr of a rubber component selected from the group of styrene-butadiene rubber (SBR), polybutadiene rubber (BR), natural rubber (NR) or a mixture thereof; ≥ 1 phr to ≤ 50 phr of a thermoplastic elastomer (TPE) with a glass transition temperature of ≥ -30 °C (measured by DSC, according to ISO 22768), the composition further comprises an at least partially aliphatic resin component and the composition further comprises a blocked mercaptosilane and/or an unblocked mercaptosilane.
