A pneumatic tire comprising a textile cord reinforced rubber component is disclosed. The rubber component comprises a textile cord contacting a rubber composition. The rubber composition comprises:
from 20 to 45 phr of a solution polymerized styrene-butadiene rubber having a bound styrene content ranging from 5 to 25 percent by weight, a vinyl-1,2 content ranging from 5 to 40 weight percent based on the butadiene content, and a Tg ranging from -85 to -50 °C;
from 55 to 80 phr of a polyisoprene rubber selected from the group consisting of natural rubber and synthetic polyisoprene rubber;
from 20 to 60 phr of a filler selected from carbon black, silica, and prehydrophobated silica;
from 1 to 10 phr of a resin selected from the group consisting of carbamic resins, alkyl phenol formaldehyde resins, and phenol formaldehyde resins; and
from 0.5 to 5 phr of a methylene donor.
