    摘要： A tread is configured to have three rows of tread elements, a center row and a pair of shoulder rows, the center row forming a circumferential rib positioned at an equatorial centerplane of the tread. Each shoulder row has a repeating circumferential array of upwardly extending elongate groove fingers, adjacent groove fingers within the repeating array of each shoulder row of groove fingers being connected by at least one laterally extending channel. An array of serrations line each longitudinal side of the channels, each serration defined by inward tapering serration sidewalls extending to a serration base surface. Each channel is submerged below an outward tread surface such that the submerged channel will emerge as the tread wears down.

    摘要： A tire is configured having first and second shoulder rows of shoulder tread elements opposite respective first and second interior rows of interior tread elements, separated respectively by circumferentially extending, zig-zag shaped first and second grooves within a tire tread region. Each groove is defined by opposed shoulder tread elements and interior tread elements and includes a circumferentially continuous see-through central groove portion extending parallel to a circumferential centerplane of the tread. The see-through circumferential grooves communicate with angular intermediate and shoulder lateral grooves having a relatively wide mouth dimension adjacent to a respective circumferential grooves. Staggered in and out shoulder regions within the shoulder tread elements facilitate gripping edges and prevent mud clogging of the shoulder grooves.

    摘要翻译： 轮胎构造成具有第一和第二肩肩排的胎肩胎面元件，所述胎肩胎肩元件分别与轮胎胎面区域内的周向延伸的，锯齿形的第一和第二槽相对地分别相对于第一和第二内部排的内胎面元件相对。 每个槽由相对的胎肩胎面元件和内部胎面元件限定，并且包括平行于胎面的周向中心平面延伸的周向连续的透明中心槽部分。 透视周向沟槽与具有相对较宽的口部尺寸的角度中间和肩部侧向沟槽相邻，邻近相应的周向凹槽。 在胎面胎面元件内部和外侧的肩部区域交错有助于抓握边缘并防止胎肩沟槽的泥浆堵塞。
