Abstract: The pneumatic tire 1 includes a belt layer 14 that includes a circumferential reinforcing layer 145 and a pair of cross belts 142, 143. Also, the pneumatic tire 1 includes at least three or more circumferential main grooves 21 to 23 in the tread portion having groove bottoms that are convex in the groove depth direction. Also, the curvature radius RA of the groove bottom of an arbitrary first circumferential main groove 21, 22 and the curvature radius RB of the groove bottom of an arbitrary second circumferential main groove 23 have the relationship RA
Abstract translation: 充气轮胎1包括带层14，其包括周向增强层145和一对交叉皮带142,143。另外，充气轮胎1在胎面部中具有至少三个以上的周向主槽21〜23，该胎面部具有槽 在凹槽深度方向上凸起的底部。 此外，任意的第一周向主槽21,22的槽底的曲率半径RA和任意的第二周向主槽23的槽底的曲率半径RB具有关系RA
