摘要: The present invention reveals a tire having tread that is comprised of (1) 30 phr to 80 non-random styrene-butadiene rubber polymer chains are derived from styrene and 1,3-butadiene, wherein about 10 weight percent 50 the repeat units in styrene, 60 90 sequences containing 5 20 units, bound content found first half differs second by at least percent, has 1,2-vinyl which within range 8 number average molecular 200,000 475,000, glass transition temperature −82° C. −50° (2) 70 polybutadiene. formulation can optionally contain silica lignin.
