Pneumatic tire having a tread containing immiscible rubber blend and silica
摘要:
The invention is directed to a pneumatic tire having a tread comprising a vulcanizable rubber composition comprising, expressed as parts by weight per 100 parts by weight of elastomer (phr), (A) 60 to 95 phr of solution-polymerized styrene-butadiene rubber with a bound styrene content of from 35 to 45 percent by weight, a vinyl 1,2 content of from 15 to 30 percent by weight based on the butadiene content, and a Tg of from about −40° C. to about −20° C.; (B) 5 to 40 phr of cis-1,4 polybutadiene having a Tg of from −95° C. to −105° C. (C) 50 to 150 phr of silica; (D) 30 to 70 phr of processing oil; and (E) 0.5 to 20 phr of a sulfur containing organosilicon compound.
