    • A tread wear indicator may be molded into the shoulder region of a tire tread and may have three symbols. Two of the symbols may be alphanumeric characters and the third symbol may surround the two symbols. All three symbols may be visible prior to wearing the tread. After the tread has been worn a first amount, the first symbol may be invisible and the second and third symbols may be visible to indicate to the user that a new tire will soon be required. After the tread has been worn a second amount, the first and second symbols may be invisible and the third symbol may be visible to indicate to the user that a new tire is required immediately.
    • 胎面磨损指示器可以模制到轮胎胎面的肩部区域中,并且可以具有三个符号。 两个符号可以是字母数字字符,第三个符号可以围绕两个符号。 所有三个符号在佩戴胎面之前可能是可见的。 在胎面磨损第一量之后,第一符号可能是不可见的,并且第二和第三符号可能是可见的,以向用户指示即将要求的新轮胎。 在胎面已经磨损第二量之后,第一和第二符号可以是不可见的,并且第三符号可以是可见的,以向用户指示立即需要新的轮胎。

    • 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.
    • 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。
