1. A rubber composition which comprises, based upon parts by weight per 100 parts by weight rubber (phr):
(A) 100 phr of at least one diene-based elastomer, (B) about 20 to about 120 phr of at least one reinforcing filler, comprised of
(1) precipitated silica or a combination of rubber reinforcing carbon black and precipitated silica (synthetic amorphous silica containing hydroxyl groups), together with a silica coupler for said precipitated silica having a moiety reactive with hydroxyl groups on said precipitated silica and another different moiety interactive with said diene-based elastomer(s), and(2) about 0.5 to about 30 phr of exfoliated graphene platelets having an average thickness in a range of from about 1 nm to about 5 nm and an average lateral dimension in a range of from about 0.1 to about 100 micrometers.
