PNEUMATIC TIRE |
摘要 |
The present invention is a pneumatic tire comprising an inner liner disposed on the inner side of the tire. The inner liner is composed of a sheet made of an elastomer composition containing a styrene-isobutylene-styrene triblock copolymer by more than or equal to 7 percent by mass and less than or equal to 93 percent by mass and an isobutylene-based modified copolymer containing a ²-pinene component by more than or equal to 7 percent by mass and less than or equal to 93 percent by mass. In the inner liner, a ratio Gs/Gb between an average thickness Gb in a bead region Rb extending from a tire largest width position to a bead toe and an average thickness Gs in a buttress region Rs extending from the tire largest width position to a corresponding position Lu at a belt layer end is 0.30 to 0.75. |
