    • The present invention is directed to a pneumatic tire 1, comprising at least one pair of parallel annular beads 3; at least one carcass ply wrapped 5 around said beads 3; a tread 7; and first and second sidewalls 9 disposed between said tread 7 and one of said at least one pair of beads 3. In accordance with an embodiment of the invention, the tread comprises tread blocks 11 and/or tread ribs 12, wherein the tread blocks 11 and/or tread ribs 12 comprise sipes 13 extending essentially in an axial direction A of the tire 1, the sipes 13 consisting of an upper portion 15 essentially aligned with the radial direction R of the tire and a lower portion 17 inclined in the direction of rotation D of the tire 1.

    • A tread for a pneumatic tire includes a first circumferentially continuous groove, a second circumferentially continuous groove, a central rib interposed between the two circumferentially continuous grooves and extending continuously around a circumference of the tread, a first circumferentially extending shoulder rib disposed laterally outside of the first circumferentially continuous groove, and a second circumferentially extending shoulder rib disposed laterally outside of the second circumferentially continuous groove. The central rib has a plurality of circumferentially spaced sipes arranged in a first circumferential row and a second circumferential row. The sipes of the first row originate at the first circumferentially continuous groove and the sipes of the second row originate at the second circumferentially continuous groove. The sipes of both the first and second rows extend axially inward to a circumferentially extending and continuous variable center groove. The variable center groove has a minimum circumferentially extending opening at a radially outermost portion. As the tread wears and the radially outermost portion of the tread moves radially inward, the circumferentially extending opening of the variable center groove widens to a maximum circumferentially extending opening greater than the minimum circumferentially extending opening.
    • 用于充气轮胎的胎面包括第一周向连续的槽,第二周向连续的槽,插入在两个周向连续的槽之间并围绕胎面的圆周连续延伸的中心肋,第一周向延伸的肩肋, 第一周向连续的槽,以及设置在第二周向连续槽的横向外侧的第二周向延伸的肩肋。 中央肋具有布置在第一圆周排和第二圆周排中的多个周向间隔开的刀槽花纹。 第一列的刀槽花纹起始于第一周向连续的槽,并且第二列的刀槽花纹起始于第二周向连续的槽。 第一和第二列的刀槽花纹沿轴向向内延伸到周向延伸和连续的可变中心槽。 可变中心槽在径向最外侧部分具有最小的周向延伸开口。 当胎面磨损并且胎面的径向最外部部分径向向内移动时,可变中心槽的周向延伸的开口变宽到大于最小周向延伸开口的最大周向延伸的开口。
