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) 100 phr of a solution polymerized styrene-butadiene rubber having a glass transition temperature (Tg) ranging from −85° C. to −50° C.; (B) from 1 to 30 phr of a process oil; (C) from 20 to 80 phr of a hydrocarbon resin having a Tg of at least 30° C.; and (D) from 90 to 150 phr of silica.
