Rubber compositions and treads made from such rubber compositions, the rubber composition based upon a cross-linkable rubber composition, the cross-linkable rubber composition having between 15 phr and 45 phr of a modified styrene butadiene rubber, between 55 phr and 85 phr of a polyisoprene rubber and no more than 5 phr of a third diene rubber component. Such rubber compositions may further include between 35 phr and 60 phr of a silica reinforcing filler and a sulfur curing system. The modified styrene butadiene rubber that is useful for the rubber compositions disclosed herein have a glass transition temperature of no more than −70° C. and is modified with an active moiety that interacts with the silica.
