Claim 0:
1. A pneumatic tire comprising a vulcanizable rubber composition, the vulcanizable rubber composition comprising:
from 70 to 90 phr of a first low Tg functionalized solution polymerized styrene-butadiene rubber having a glass transition temperature Tg1 ranging from −70 to −55° C.;
from 10 to 30 phr of a second low Tg functionalized solution polymerized styrene-butadiene rubber having a glass transition temperature Tg2 ranging from −100 to −70° C.;
wherein Tg2−Tg1 is at least 10° C. but less than 30° C.;
wherein the rubber composition is further devoid of a homopolymer of butadiene;
10 to 30 phr of an additional styrene-butadiene rubber with a Tg ranging from −20 to −40° C.;
from 50 to 150 phr of silica;
from 0 to 50 phr of a hydrocarbon resin; and
from 10 to 50 phr of an oil.
