    • A pneumatic tire according to the present invention includes a tread surface having a tire rotation direction designated in one direction. The tread surface has a straight main groove extending in a circumferential direction of the tire in the center, and lateral grooves obliquely extending in a width direction of the tire on both sides thereof, defining blocks thereon. On both sides of the straight main groove, left and right slant main grooves are arranged to cross three or more lateral grooves. Both ends of-the slant main grooves are positioned within the blocks, and the groove width thereof is gradually enlarged from both end portions toward the center portion of the slant main groove. The inclination angle of the slant main grooves relative to the tire circumferential direction is set in a range of 10 to 45°, and the maximum groove width thereof is set to 80 to 110% of the groove width of the straight main groove.
    • 根据本发明的充气轮胎包括具有沿一个方向指定的轮胎旋转方向的胎面表面。 胎面表面具有在中心沿轮胎的周向延伸的直的主槽,在其两侧沿轮胎的宽度方向倾斜延伸的横向槽,在其上限定块。 在直的主槽的两侧,左右倾斜的主槽被布置成与三个或更多个横向槽交叉。 倾斜主槽的两端位于块内,其宽度从两个端部向斜槽主槽的中心部分逐渐扩大。 倾斜主槽相对于轮胎周向的倾斜角度设定在10〜45°的范围内,其最大槽宽设定为直主槽的槽宽度的80〜110%。
