    • 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。
