Abstract
An elastomeric composition is disclosed. The elastomeric composition includes, per 100 parts by weight of rubber (phr): about 30 to about 70 phr of polybutadiene having a cis-1,4 linkage content of at least 95%; about 30 to 70 phr of natural rubber or polyisoprene; about 20 to 50 phr of a processing oil; a curative agent; an antioxidant; about 50 to about 80 phr filler; a silane coupling agent; and about 5 to about 30 phr of a polymer selected from the group consisting of ethylene-propylene-diene terpolymer, butyl rubber, poly(isobutylene-co-para-methylstyrene) and poly(isobutylene-co-para-methylstyrene-co-isoprene) terpolymer. The polymer based on ethylene-propylene-diene terpolymer, butyl rubber, poly(isobutylene-co-para-methylstyrene) and poly(isobutylene-co-para-methylstyrene-co-isoprene) terpolymer may be functionalized.
