充气轮胎
摘要：
提供一种充气轮胎，该充气轮胎具备选择性地配置于胎体层与内衬层的层间的一部分的部分结合橡胶层，能够一边维持干燥路面上的操纵稳定性一边减少轮胎重量以及滚动阻力。在胎体层(4)与内衬层(9)的层间的、除了胎面部(1)的中央区域之外的轮胎宽度方向两侧的区域分别选择性地配置了内侧结合橡胶层(11)和外侧结合橡胶层(12)，将上述内侧结合橡胶层(11)和外侧结合橡胶层(12)的轮胎赤道侧的端部分别配置于距带束层(7)的轮胎宽度方向最外侧的端部起轮胎宽度方向内侧10mm～25mm的范围，在内侧结合橡胶层(11)与外侧结合橡胶层(12)使橡胶厚度不同，使外侧结合橡胶层(12)的橡胶厚度(t2)为内侧结合橡胶层(11)的橡胶厚度(t1)的120％～200％。
摘要（英）：

A pneumatic tire is provided in which an inner tie rubber layer and an outer tie rubber layer are selectively disposed between a carcass layer and an innerliner layer in a region on both sides in a tire width direction excluding a center region of a tread portion. End portions of the inner tie rubber layer and outer tie rubber layer on a tire equator side are disposed within a range of from 10 mm to 25 mm on an inner side in the tire width direction from an end portion on an outermost side in the tire width direction of a belt layer. A rubber thickness t1 of the inner tie rubber layer differs from a rubber thickness t2 of the outer tie rubber layer. A rubber thickness of the outer tie rubber layer is from 120% to 200% a rubber thickness of the inner tie rubber layer.
