    • A large size pneumatic rubber tire for bad or rough roads comprises a number of main grooves in a tread of the tire arranged on both sides of a center circumferential line of the tread and in parallel with one another substantially equally oblique to the center circumferential line and a number of auxiliary grooves in the tread substantially in parallel with one another oblique in a direction opposite to the direction of the main grooves to connect the two main grooves adjacent in a circumferential direction. The main and auxiliary grooves have comparatively wide groove widths, respectively, and divide the tread into a center zone and two size zones. These zones respectively consist of circumferentially arranged respectively substantially same shaped center blocks and side blocks defined by the main and auxiliary grooves. The tire according to the invention can effectively eliminate extraordinary temperature rise in the tire without sacrificing the required performances such as wear-resistance, even if under severe operating conditions.
    • 用于不良或粗糙道路的大型气动橡胶轮胎包括布置在胎面的中心圆周线的两侧上的轮胎的胎面中的多个主槽,并且彼此大致平行于中心圆周线, 在胎面基本上彼此平行的多个辅助槽沿与主槽的方向相反的方向倾斜以连接沿圆周方向相邻的两个主槽。 主槽和辅助槽分别具有相对宽的槽宽度,并将胎面分成中心区和两个尺寸区。 这些区域分别由周向布置的大致相同的形状的中心块和由主槽和辅助槽限定的侧块组成。 根据本发明的轮胎,即使在恶劣的工作条件下也能有效地消除轮胎的非常温升,而不会牺牲耐磨性等性能。
