The effects of the dosage of brominated butyl rubber(BIIR) and the reinforcing agent Creat E on the air permeability of tire inner liner tire were studied. The results showed that the gas barrier properties of the inner liner compound with 90 or 100 phr of BIIR were better than that of the compound with 80 phr of BIIR. Better performance to cost ratio was achieved by adding Creat E in the compound directly or to replace part of carbon black.
