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 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.
