This invention reveals a pneumatic tire comprising a generally toroidal-shaped carcass with an outer circumferential tread, two spaced beads, at least one ply extending from bead to bead and sidewalls extending radially from and connecting said tread to said beads, and an innerliner which covers the inner surface and which is comprised of a halobutyl rubber, a filler and lignin. The incorporation of lignin into the innerliner prevents migration of moisture into the tire carcass which can lead to corrosion and consequential delamination of steel cords within the tire. Normally the lignin will be included in such innerliner formulations in an amount which is within the range of 1 phr to 20 phr. Lignin can also be used to protect the steel belts by incorporating it into other tire components located between the innerliner and the belts.
