Abstract:
A pneumatic tire is provided with an inner liner which improves the resistance to air permeability, the bending fatigue properties, and the crack resistance. A pneumatic tire is provided with an inner liner inside the tire. The inner liner is characterized in that the inner liner is configured from at least a layer of polymer sheet containing a styrene-isobutylene-styrene triblock copolymer. The average thickness (Gs) of buttress regions (Rs) extending from the positions of the maximum width of the tire to corresponding positions (Lu) at the ends of a belt layer is less than the average thickness (Gb) of bead regions (Rb) extending from the positions of the maximum width of the tire to bead toes.
