Claim 0:
1. A vulcanizable rubber composition comprising, based on 100 parts per weight (phr) of elastomer:
(A) elastomers selected from the group consisting of styrene-butadiene; polybutadiene; natural rubber; polyisoprene; and mixtures thereof;
(B) from about 5 to about 15 phr of an olefin-maleic anhydride copolymer resin comprising side chain functional groups along the resin backbone and characterized by an MA; olefin mole ratio between from about 0.20 and about 8 and an average molecule weight between from about 5 and about 30,000 g/mol; and
(C) from 1 to about 5 phr of a processing additive capable of promoting connections between the functional groups to form an interpenetrating or ionic network.
