The elastomeric compositions comprise 100 phr (parts by weight per hundred parts of total elastomer) diene elastomers; about 0 to about 80 phr of processing oil; 0 to about 80 phr of a hydrocarbon resin; about 60 to about 140 phr of filler; a curative agent; and about 5 to about 30 phr of a silane functionalized propylene-ethylene-diene terpolymer. The silane functionalized propylene-ethylene-diene terpolymer comprises from about 2 wt. % to about 40 wt. % of ethylene and/or C-Cα-olefins derived units, from 0.5 to 10 wt % of diene derived units, and a silane coupling agent. The present elastomeric compositions are useful as tire tread compositions for improved tire performance.",
