Abstract:
The present invention is directed to a pneumatic tire having a tread comprising a vulcanizable rubber composition comprising, based on 100 parts by weight of elastomer (phr), (A) from about 20 to about 60 phr of a solution polymerized styrene-butadiene rubber having a glass transition temperature (Tg) ranging from −85° C. to −50° C.; (B) from about 45 to about 80 phr of a polybutadiene having a cis 1,4 content greater than 95 percent and a Tg ranging from −80 to −110° C.; and (C) from 0 to 20 phr of a process oil; (D) from 55 to 80 phr of a resin selected from the group consisting of C5/C9 resins and DCPD/C9 resins, the resin having a Tg greater than 30° C.; and (E) from 110 to 160 phr of silica.
