An elastomeric composition comprising (i) at least one elastomer; (ii) at least one filler comprising silica; (iii) and at least one silane-functionalized hydrocarbon polymer modifier (Si-HPM); wherein the Si-HPM comprises an interpolymer comprising at least one monomer chosen from piperylenes, cyclic pentadienes, aromatics, limonenes, pinenes, and amylenes, and further comprises at least one functional group comprising a silane structure wherein the interpolymer, prior to functionalization, has a weight average molecular weight of 2500 to 25,000 g/mole and a number average molecular weight of 900 to 3,000 g/mole. |
