    • A pneumatic tire 1 according to the present invention includes a plurality of turbulence generation ridges 13 which extend on a surface of a tire side portion 7 in a tire-radial direction and which are arranged at a pitch in a tire-circumferential direction. A protrusion 15 rising from the surface 7a of the tire side portion 7 is formed in the tire side portion 7. Either an inner end portion 13A of the turbulence generation ridge 13 or an outer end portion 13B of turbulence generation ridge 13 is smoothly continuous to a surface of the protrusion 15. An inner end height (H1), which is a height of the inner end portion 13A from the surface 7a of the tire side portion 7, is larger than an outer end height (H2), which is a height of the outer end portion 13B from the surface 7a of the tire side portion 7.

    • A pneumatic tire is provided, which readily achieves rain groove wandering resistance without sacrificing wet performance and other performances. Plural steep-angle grooves 16 are provided at opposite sides of the tire equatorial plane CL. Each steep-angle groove 16 is inclined at an angle of not more than 45 degrees relative to the tire circumferential direction, such that the steep-angle groove 16 contacts the ground from a tire equatorial plane CL side. Recessed portions 36 are formed along a tread surface side edge of a land portion adjacent to an inner side in a tire axial direction of the steep-angle transverse groove 16. A depth of the recessed portion 36 gradually increases and a width thereof gradually decreases along a middle portion in a longitudinal directional toward end portion at the tire equatorial plane CL of the steep-angle transverse groove 16. This pattern smoothly drains water around the center of the ground contacting area from the tire equatorial plane CL side to the steep-angle transverse grooves 16 through the recessed portion 36. Although the number of circumferential grooves 14 is small, high wet performance can be obtained. Further, since the number of the circumferential groove 14 is small, rain groove wandering can be suppressed.
    • 提供了一种充气轮胎,其容易实现雨沟游走性,而不会牺牲湿性能等性能。 在轮胎赤道平面CL的相对侧设置有多个陡角槽16。 每个陡峭角槽16相对于轮胎周向以不大于45度的角度倾斜,使得陡角槽16从轮胎赤道面CL侧接触地面。 凹陷部分36沿着与陡角横向槽16的轮胎轴向方向的内侧相邻的陆部的胎面表面侧边缘形成。凹部36的深度逐渐增加,并且其宽度逐渐减小 在陡角横向槽16的轮胎赤道平面CL处的纵向方向端部的中间部分。该图案将地面接触区域的中心周围的水从轮胎赤道平面CL侧平滑地排出到陡度角 通过凹部36的横向槽16.虽然圆周槽14的数量少,但是可以获得高的湿性能。 此外,由于周向槽14的数量少,因此可以抑制雨沟的流动。
