Pneumatic tire

A pneumatic tire having a tread comprising a vulcanizable rubber composition comprising, based on 100 parts by weight of elastomer (phr),

• (A) from about 30 to about 50 phr of a first solution polymerized styrene-butadiene rubber having a glass transition temperature (Tg) ranging from −80° C. to −50° C. and functionalized with an alkoxysilane group and a thiol group;
• (B) from about 30 to about 50 phr of a second solution polymerized styrene-butadiene rubber having a glass transition temperature (Tg) ranging from −40° C. to −10° C. and functionalized with an alkoxysilane group and a primary amine group;
• (C) from 0 to about 40 phr of a polyisoprene having a cis 1,4 content greater than 95 percent selected from the group consisting of natural rubber and synthetic polyisoprene;
• (D) from 20 to 60 phr of a hydrocarbon resin having a Tg of at least 30° C.;
• (E) from 40 to 80 phr of an oil;
• and
• (F) from 120 to 180 phr of silica.
