Provided is a pneumatic tire that improves steering stability during high-speed travel while maintaining good riding comfort. The pneumatic tire has a tread portion (2). The cap belt cord (12) of the cap belt layer (9) is a hybrid cord obtained by twisting a first monofilament (16) and a second monofilament (17). The maximum thickness (t1) of the topping rubber (13) on the outside of the cap cord (12) in the radial direction of the tire is 1.0 mm or less in a region on the inside of the first circumferential groove (10) in the radial direction of the tire. The minimum distance (d1) from the bottom of the first circumferential groove (10) to the outer surface of the cap ply (9) in the radial direction of the tire is 2.0 mm or less. The distance (d2) in the tire normal direction from the groove edge (10e) of the first circumferential groove (10) to the outer surface of the cap ply (9) is 15.0 mm or less.
提供在维持良好的乘坐舒适性的同时提高高速行驶时的操纵稳定性的充气轮胎。充气轮胎具有胎面部(2)。冠带层(9)的冠带帘线(12)是捻合第1单丝(16)和第2单丝(17)而得的混合帘线。在第1周向槽(10)的轮胎半径方向内侧的区域,冠带帘线(12)的轮胎半径方向外侧的贴胶橡胶(13)的最大的厚度(t1)为1.0mm以下。从第1周向槽(10)的槽底到冠带层(9)的轮胎半径方向的外表面的最小的距离(d1)为2.0mm以下。从第1周向槽(10)的槽缘(10e)到冠带层(9)的外表面的轮胎法线方向的距离(d2)为15.0mm以下。
