A method that includes providing a modified rubber component selected from a modified polybutadiene rubber (BR), a modified styrene-butadiene rubber (SBR) or combinations thereof, wherein the modified rubber component has been modified with a functional group having a heteroatom selected from oxygen, nitrogen, silicon or combinations thereof and wherein the rubber component has a Tg of between −80° C. and −110° C. and selecting an efficient plasticizing resin. An efficient plasticizing resin is one that when included in a mixture of the modified rubber component and 67 phr of the efficient plasticizing resin, causes a Tg of the mixture to be at least 14° C. higher than the Tg of the modified rubber component itself. Methods may further include mixing between 70 phr and 100 phr of the modified rubber component with between 30 phr and 130 phr of the efficient plasticizing resin.
