    • A tread for a heavy vehicle tire which, when new, has a tread surface, this tread including over at least a first axial part (M) of the tread at least one wavy groove with waviness in the thickness of the tread and continuous in a first direction and a plurality of wavy grooves with waviness in the thickness of the tread and continuous in a second direction, the wavy grooves in the second direction being connected to at least one wavy groove in the first direction, and over at least a second axial part (B) of the tread at least one wavy groove with waviness in the thickness of the tread and continuous in a third direction and a plurality of wavy grooves with waviness in the thickness of the tread and continuous in a fourth direction, the wavy grooves of this second axial tread part (B) oriented in the fourth direction being connected to at least one wavy groove in the third direction, this tread being such that, when new, the open parts opening onto the tread surface of the first axial part (M) are connected to one another to form a continuous surface network and in that the open parts opening onto the tread surface of the second axial part (B) are disjointed from one another, and beyond a part-wear condition, the open parts opening onto a new tread surface of the second axial part (B) are connected to one another to form a continuous surface network and in that the open parts opening onto the new tread surface of the first axial part (M) are disjointed from one another.
    • 一种重型车辆轮胎的胎面,当新的轮胎具有胎面表面时,该胎面包括在胎面的至少一个第一轴向部分(M)上的至少一个波纹槽,胎面的厚度为波纹,并且在胎面 第一方向和多个在胎面的厚度上具有波纹并且在第二方向上连续的波状凹槽,第二方向上的波浪形凹槽在第一方向上连接至少一个波浪形凹槽,并且在至少第二轴向上连接 所述胎面的部分(B)具有至少一个具有波纹,胎面厚度和第三方向连续的波浪槽,并且在胎面的厚度上具有波纹并在第四方向上连续的多个波状凹槽, 在第四方向上定向的第二轴向胎面部分(B)沿第三方向连接到至少一个波浪形槽,该胎面使得当新的时候,打开第一轴向的胎面表面上的开口部分 部分(M)彼此连接以形成连续的表面网络,并且打开到第二轴向部分(B)的胎面表面上的开放部分彼此不相交,并且超出部分磨损状态,打开 通向第二轴向部分(B)的新的胎面表面上的部分彼此连接以形成连续的表面网络,并且打开到第一轴向部分(M)的新的胎面表面上的开口部分不与一个 另一个。
