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) 100 phr of a solution-polymerized styrene-butadiene rubber with a bound styrene content of from 20 to 50 percent by weight, a vinyl 1,2 content of from 10 to 40 percent by weight based on the rubber weight, and a Tg of from about −40° C. to about −10° C.; (B) 5 to 60 phr of a low PCA process oil having a polycyclic aromatic content of less than 3 percent by weight as determined by the IP346 method; (C) 90 to 150 phr of silica having a CTAB specific surface area (SCTAB) of between 40 and 525 m2/g, a BET specific surface area (SBET) of between 45 and 550 m2/g; (D) 10 to 20 phr of sulfur containing organosilicon compound; (E) 5 to 30 phr of a polyterpene resin, and (F) less than 10 phr of carbon black.
