<p>PROBLEM TO BE SOLVED: To provide a pneumatic tire including an inner liner having curing adhesive force compatible to adjacent rubber and having the increase of rolling resistance reduced, and having high air permeability resistance and bent crack growth resistance, and air-in generation suppressed.SOLUTION: A pneumatic tire 1 includes an inner liner 9 in the tire inside of a carcass ply 6 hung between a pair of beads 4. The inner liner includes a first layer made of a first polymer composition including SIBS and formed with a thickness of 0.05 mm or more to 0.6 mm or less, and a second layer made of a second polymer composition including SIB and formed with a thickness of 0.01 mm or more to 0.3 mm or less. One of the first polymer composition and the second polymer composition includes 10 mass % or more to 99.5 mass % or less of SIBS modified copolymer in a polymer component. The second layer is disposed to contact with a rubber layer of the carcass ply. The inner liner has a thickness Gc at a crown center position Pc larger than a thickness Ge at a shoulder position Pe.</p> |
