    • 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.
    • 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。

    • A new pneumatic radial ply truck tire 10 for use on steering axles has a tread 12 with four circumferential grooves 14 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 and bottom potions 30, 32. The top portions 30 have straight sides 42 that are angled at top angles A1. The middle portions 32 also have straight sides 44 that are angled at bottom angles A2. To provide the grooves 14 with a general V-shape, it is preferred that the bottom angles A2 be greater than their respective top angles A1. Stone penetration protectors 34 are positioned within the circumferential grooves 34 to protect the tread 12 and the belt-package 13 from stone damage. The lateral grooves 20 that extend across the two riding rows 26 and the center row 28 have top portions 50 and bottom portions 52. The top portions 50 have first widths W1 and first depths D1 and the bottom portions 52 have second widths W2 and second depths D2 that extend to at least 85% 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 center row 28 and the riding rows 26 have radiused tread surfaces 27 with a tread arc radius TAR. The shoulder rows 24 have flat linear tread surfaces 25 that are tangent to the tread arc radius TAR. This provides for outside edges 56 of the shoulder rows 24 that have a shoulder fall-off distance X2 that is less than the shoulder fall-off distance X1 that would occur if the tread was made fully with the tread arc radius TAR. This multi-radii shape reduces irregular wear.
    • 用于转向轴的新的气动径向搭载卡车轮胎10具有胎面12，胎面12具有四个周向槽14，胎面12将胎面12分成一对肩部行24，一对行进行26和中心行28.横向槽20 将排分成块元件22.中心线槽14和肩部槽16具有顶部和底部部分30,32。顶部部分30具有以顶角A1成角度的直边42。 中间部分32还具有在底角A2处成角度的直边44。 为了提供具有一般V形的凹槽14，优选底角A2大于它们各自的顶角A1。 石头穿透保护器34定位在周向槽34内，以保护胎面12和带束包装13免受石头损坏。 延伸穿过两个行列26和中心行28的横向槽20具有顶部50和底部52.顶部50具有第一宽度W1和第一深度D1，并且底部52具有第二宽度W2和第二深度 D2，其延伸至胎面无滑动深度D的至少85％。中心行28和搭乘行26形成为胎面弧半径TAR。 中心排28和搭乘排26具有胎面圆弧半径TAR的圆弧形胎面27。 肩排24具有与胎面弧半径TAR相切的平坦的线性胎面25。 这提供了具有肩部离开距离X2的肩部行24的外边缘56，其小于如果胎面完全具有胎面弧半径TAR时将发生的肩部脱落距离X1。 这种多半径形状减少不规则磨损。
