Abstract:
1. A tire having at least one component of a rubber composition comprised of, based upon 100 parts by weight of elastomer (phr), (A) 100 phr of elastomers comprised of: (B) about 35 to about 100 phr of particulate reinforcement comprised of (C) a coupling agent having: (D) about 2 to about 10 phr of a starch/plasticizer composite comprised of starch and plasticizer therefor of a weight ratio in a range of about 0.05/1 to about 4/1, wherein said starch/plasticizer composite has a softening point in a range of about 110° C. to about 170° C. or said coupling agent as a combination of a bis-(3-triethoxysilylpropyl) polysulfide having an average of from 2 to 2.5 connecting sulfur atoms in its polysulfidic bridge and a bis-(3-triethoxysilylpropyl) polysulfide having an average of from 3 to 4 connecting sulfur atoms in its polysulfidic bridge, wherein said polysulfide having an average of from 2 to 2.5 connecting sulfur atoms it its polysulfidic bridge is blended with said rubber composition in the absence of sulfur and sulfur vulcanization accelerator and wherein said polysulfide having an average of from 3 to 4 connecting sulfur atoms in its polysulfidic bridge is thereafter blended with said rubber composition in the presence of sulfur and at least one sulfur vulcanization accelerator.
