Abstract
The tire of the present invention is a tire having an inner liner composed of a rubber composition for an inner liner which is excellent in steering stability, fuel efficiency and a balance of physical properties while maintaining air permeation resistance and durability. The rubber composition for an inner liner comprises a rubber component and additives, wherein E* (MPa) and tan δ measured at a temperature of 70° C., an initial strain of 10% and a dynamic strain of 2% satisfy the following formulas (1) to (3), an air permeation coefficient is not more than 12.00×10cm·cm/(cm·s·Pa), and TB (MPa) and EB (%) as measured in accordance with JIS K6251 satisfy the following formulas (4) and (5).*/tan δ>17  Formula (1):2.5<*<5  Formula (2):tan δ<0.15  Formula (3):>450  Formula (4):>10,000  Formula (5):
