    Abstract: A pneumatic tire includes on a tread a plurality of circumferential main grooves extending in the tire circumferential direction, and a plurality of land portions formed by being partitioned by the circumferential main grooves. A protrusion is formed on a groove bottom of at least one of the circumferential main grooves. The protrusion continuously extends in a groove-length direction of the circumferential main groove, and a height h1 of the protrusion varies in a wavelike form along the groove-length direction. Moreover, junctions each of which couples the protrusion onto at least one of groove walls of the circumferential main groove are formed on the groove bottom of the circumferential main groove.

    Abstract: A new pneumatic radial ply truck tire 10 for use on steering axles has a tread 12 with a pair of centerline grooves 14 and a pair of shoulder grooves 16 that divide the tread 12 into a pair of shoulder rows 24, a pair of riding rows 26 and a center row 28. Lateral grooves 20 divide the rows into block elements 22. The centerline grooves 14 and shoulder grooves 16 have top, middle and bottom potions 30, 32, 34 and 36, 38, 40. The top portions 30, 36 have straight sides 42, 48 that are angled at top angles A1, A2 respectively. The middle portions 32, 38 also have straight sides 44, 50 that are angled at middle angles A3, A4 respectively. To provide the grooves 14, 16 with a general V-shape, it is preferred that the middle angles A3, A4 be greater than their respective top angles A1, A2 respectively. The bottom portions 34, 40 are U-shaped and have bottom widths X1 and bottom depths D1, D2 respectively. These U-shaped bottom portions 34, 40 are wide enough to permit a tread gauge to be inserted for measuring the non-skid depth yet, are narrow enough to prevent stones of significant size from entering. The lateral grooves 20 that extend across the two riding rows 26 and the center row 28 have top portions 58, 64 and bottom portions 60, 66. The bottom portions 60, 66 have second widths W2, W4 and second depths D4, D6 that extend to at least 50% of the tread non-skid depth D. The center row 28 and the riding rows 26 are formed at a tread arc radius TAR. The shoulder rows 24 have inside edges lowered a first distance D10 with respect to the tread arc radius TAR and outside edges that are raised a second distance D11 with respect to the tread arc radius TAR. This single radius plus mixed shoulder off-set design reduces irregular wear and helps in achieving equal pressure distribution across the surface of the tread 12.

    Abstract translation: 用于转向轴的新型气动径向搭载卡车轮胎10具有胎面12，胎面12具有一对中心线槽14和一对胎肩槽16，该胎肩槽16将胎面12分成一对肩部行24，一对骑行行26 横列20将行分成块元件22.中心线槽14和肩部槽16具有顶部，中间和底部部分30,32,34,36,38,40。顶部30,36 具有分别以顶角A1，A2成角度的直边42,48。 中间部分32,38也具有分别以中间角度A3，A4成角度的直边44,50。 为了提供具有一般V形的槽14,16，优选的是，中间角A3，A4分别大于它们各自的顶角A1，A2。 底部34,40是U形的，并且分别具有底部宽度X1和底部深度D1，D2。 这些U形底部34,40足够宽以允许插入踏板以测量非滑动深度，并且足够窄以防止具有相当大尺寸的石块进入。 延伸穿过两个行列26和中心行28的横向凹槽20具有顶部58,64和底部60,66。底部60,66具有第二宽度W2，W4和第二深度D4，D6，其延伸 到胎面非滑动深度D的至少50％。中心排28和搭乘排26形成为胎面弧半径TAR。 肩部行24的内边缘相对于胎面弧半径TAR降低第一距离D10，相对于胎面弧半径TAR将第二距离D11升高的外边缘降低。 该单个半径加上混合肩部偏离设计减少了不规则磨损，并且有助于在胎面12的表面上实现相等的压力分布。

    Abstract: A pneumatic tire includes a plurality of protrusions on a bottom of each of the grooves. The height of the protrusion is variable in a profile of the protrusion in a circumference direction of the pneumatic. The protrusion has at least one peak portion that protrudes away from a center of the pneumatic tire. The pneumatic tire further includes a connection member between the protrusion and an adjacent one of the lands, the connection member having a first end toward the land and a second end toward the peak portion, a height of the first end from the bottom of the groove being larger than that of the second end.
