Abstract
A tire component formed from a rubber composition comprises a majority weight percent of renewable materials. The rubber composition comprises, based on 100 parts per weight (phr) of elastomer: a blend of at least two rubber elastomers selected from a group consisting of: greater than 50 phr of at least one mass balanced polymer; at least one bio-derived plasticizer; and a bio-derived filler system comprising silica and carbon black. The carbon black filler is at least partially derived from a bio-based feedstock prior to its addition to the rubber composition. The resin and the silica are also derived from renewable materials.
