A cross-linkable rubber composition comprises: a rubber component selected from the group of styrene-butadiene rubber (SBR), polybutadiene rubber (BR), natural rubber (NR) or a mixture thereof, a filler component, a silane coupling agent and a process oil component comprising an unsaturated fatty acid triglyceride where at least one carbon-carbon double bond in the molecule has been subjected to one or more chemical reactions ("modified unsaturated oil"). The filler component comprises silica, the filler component comprises ≥ 0 phr to ≤ 25 phr of carbon black, as the modified unsaturated oil in the process oil component is used: an epoxide of an unsaturated fatty acid triglyceride, a stoichiometrically complete or partial reaction product of an epoxide of an unsaturated fatty acid triglyceride with a molecule containing a nucleophilic group, or a mixture thereof and the process oil component comprises ≥ 0 phr to ≤ 25 phr of treated distilled aromatic extract (TDAE), mild extracted solvate (MES) and naphthenic (NAP) oils. |
