Abstract: 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.

Abstract: An elastomeric composition is disclosed. The elastomeric composition includes, per 100 parts by weight of rubber (phr): about 30 to about 50 phr of polybutadiene having a cis-1,4 linkage content of at least 95%; about 40 to about 60 phr of styrene/butadiene copolymer; about 0 to about 20 phr of natural rubber or polyisoprene; about 0 to about 30 phr of a processing oil; about 10 to about 30 phr of a hydrocarbon resin; about 50 to about 75 phr of a filler; a curative agent; an antioxidant; a silane coupling agent; and about 5 to about 30 phr of a propylene-ethylene-diene terpolymer containing from about 2 wt % to about 30 wt % of ethylene and/or C4-C20 α-olefins derived units.

The elastomeric composition includes, per 100 parts by weight of rubber (phr): about 30 to about 50 phr of polybutadiene having a cis-1,4 linkage content of at least 95%; about 40 to about 70 phr of styrene/butadiene copolymer; about 0 to about 20 phr of natural rubber or polyisoprene; about 0 to about 30 phr of a processing oil; about 10 to about 30 phr of a hydrocarbon resin; about 50 to about 75 phr of a filler; a curative agent; an antioxidant; a silane coupling agent; and about 5 to about 30 phr of a butyl copolymer rubber containing about 85 to about 99.5 mol % C4-C7 isoolefin(s) and from about 0.5 to about 15 mol % C4-C14 conjugated dienes.
