    • A studless tire comprises tread blocks having a narrow-width center portion, a heel-side increasing-width portion and a toe-side increasing-width portion, wherein the axial width of the block becomes minimum in the narrow-width portion and increases toward the heel edge and toe edge in the heel-side and toe-side increasing-width portions, and the minimum width in the narrow-width portion being in the range of from 0.5 to 0.9 times the average of the maximum width in the heel-side increasing-width portion and the maximum width in the toe-side increasing-width portion, whereby the stress produced in the block rubber when a braking force or driving force acts thereon increases the apparent block rigidity to decrease the block edge lifting and thereby uneven wear can be decreased.
    • 无钉防滑轮胎包括具有窄宽度中心部分,后跟侧增宽部分和趾部增加宽度部分的胎面花纹块,其中,在窄宽度部分中块的轴向宽度变得最小,并且朝向 后跟侧和脚趾侧增加宽度部分中的跟部边缘和脚趾边缘,并且窄边宽度部分中的最小宽度在后跟部分的最大宽度的平均值的0.5至0.9倍的范围内, 侧增宽部分的最大宽度和趾侧增加宽度部分的最大宽度,由此当制动力或驱动力作用在其上时在块橡胶中产生的应力增加了表观块刚度以减小块边缘提升,从而不均匀 磨损可以减少。

    • A heavy duty pneumatic tire comprising a plurality of block rows provided on a tread surface, each block row being composed of a plurality of blocks formed by a plurality of main grooves extending in a tire circumferential direction and a plurality of lateral grooves intersecting said main grooves, wherein a narrow block is provided, interposing a sub groove, in a position outside each block of block rows adjacent to an inner side of an outermost main groove in a tire width direction; and wherein a surface of said narrow block is formed to be circular-arc by setting a height of a center part of said narrow block surface in the tire circumferential direction to be equal to that of said tread surface and a height of both end parts of said narrow block surface to be lower than that of said tread surface by 1.5 to 2.5 mm.
    • 一种重型充气轮胎,包括设置在胎面表面上的多个块列,每个挡块行由多个沿轮胎周向延伸的主槽形成的块和与所述主槽相交的多个横向槽 其特征在于,在轮胎宽度方向上,在与所述最外侧主槽的内侧相邻的块排列的外侧的位置设置有副槽, 并且其中所述窄块的表面通过将所述窄块表面的在轮胎周向上的中心部分的高度设置为等于所述胎面表面的高度,并且将所述窄块体的两个端部的高度设置为圆弧 所述窄块表面比所述胎面表面低1.5-2.5mm。
