The present invention relates to a rubber composition for tire applications comprising: rubber polymer(s) comprising at least optionally-functionalized styrene-butadiene rubber (SBR) and at least one rubber selected from polybutadiene rubber (BR), natural rubber (NR), polyisoprene rubber (IR) and mixtures thereof, and at least one ester derived from renewable sources resulting from the esterification of trimer and/or dimer acids having the formula A-(COOH)q, with q being 2 or 3 and A being an acyclic, cyclic or polycyclic, saturated or unsaturated, linear or branched hydrocarbon group having from 3 to 69 carbon atoms, with acyclic or cyclic, saturated or unsaturated, linear or branched alcohols. 115-. (canceled)16. Rubber composition for tire applications comprising:rubber polymers comprising at least optionally functionalized styrene-butadiene rubber (SBR) and at least one rubber selected from polybutadiene rubber (BR), natural rubber (NR), polyisoprene rubber (IR) and mixtures thereof, and{'sub': q', 'q, 'at least one acid derived from renewable sources selected from trimer and/or dimer acids having the formula A-(COOH), with q being 2 or 3 and A being identical or different, acyclic, cyclic or polycyclic, saturated or unsaturated, linear or branched hydrocarbon groups having from 3 to 69 carbon atoms or at least one ester derived from renewable sources resulting from the esterification of trimer and/or dimer acids having the formula A-(COOH), with q being 2 or 3 and A being identical or different, acyclic, cyclic or polycyclic, saturated or unsaturated, linear or branched hydrocarbon groups having from 3 to 69 carbon atoms, with acyclic or cyclic, saturated or unsaturated, linear or branched alcohols,'}said rubber polymers comprising:from 20 to 90% by weight of styrene-butadiene rubber(s) optionally functionalized andfrom 10 to 80% by weight of at least one rubber selected from polybutadiene rubber (BR), natural rubber (NR), polyisoprene rubber (IR) and mixtures ...
