Abstract
The present invention is directed to a pneumatic tire comprising a carcass and an innerliner in direct contact with the carcass, the innerliner comprising a rubber composition comprising: 100 parts by weight of at least one elastomer; and from 25 to 100 parts by weight, per 100 parts by weight of elastomer (phr) of a polyamide having a melting temperature of less than 160° C.; wherein the elastomer exists as a continuous phase and the polyamide is dispersed as a discontinuous phase in the elastomeric continuous phase, and the innerliner is co-vulcanized with the carcass.
