An elastomeric composition is disclosed. The elastomeric composition includes, per 100 parts by weight of rubber (phr): about 5 to about 40 phr of styrene/butadiene copolymer; about 60 to about 100 phr of natural mbber or polyisoprene; a curative agent; an antioxidant; about 1 to about 20 phr carbon black; about 5 to about 40 phr plasticizing agent; about 40 to about 80 phr silica; about 1 to about 20 phr silane coupling agent and about 5 to about 30 phr of a polymer selected from the group consisting of ethyl-ene-propylene-diene terpolymer, butyl mbber, poly(isobutylene-co-para-methylstyrene) and poly(isobutylene-co-para-methylstyrene-co-isoprene) terpolymer. The polymer based on ethylene-propylene-diene terpolymer, butyl mbber, poly(isobutylene-co-para-methylstyrene) and poly(isobutylene-co-para-methylstyrene-co-isoprene) terpolymer may be functionalized.
