Abstract:
A tire having a tread of a rubber composition comprised of, based upon its rubber component,(A) 100 parts by weight (phr) of at least one solid, sulfur vulcanizable, diene-based elastomer selected from homopolymers and copolymers of conjugated diene and copolymers of at least one conjugated diene with a vinyl aromatic compound selected from styrene and alpha-methylstyrene; wherein said elastomers have a Tg of lower than +10.degree. C. and wherein at least 50 total weight percent of said elastomers have a Tg above -40.degree. C., and(B) from about 5 to about 50 phr of a liquid polymer of high vinyl polybutadiene, characterized by being a pourable liquid at a temperature in a range of about 20.degree. C. to about 25.degree. C., having a vinyl (1,2-) content in a range of about 40 to about 95 percent and a Tg in a range of about -5.degree. C. to about -40.degree. C. and blended with the said sulfur vulcanizable diene-based elastomer.
