An elastomeric composition is disclosed. The elastomeric composition includes, per 100 parts by weight of rubber (phr): about 0 to about 25 phr of poly butadiene having a cis-1,4 linkage content of at least 95%; about 75 to 100 phr of a styrene/butadiene copolymer; about 10 to about 30 phr of a processing oil; about 50 to about 70 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.
