The present invention provides for a heavy truck tire tread having a shoulder edge, shoulder groove, and shoulder rib therebetween. A plurality of sipes are in the shoulder rib and are oriented less than 20 degrees to the lateral direction. The sipes are spaced from one another between 5 to 18 millimeters in the longitudinal direction. Additionally or alternatively, the sipes are arranged so that a reference plane extends through a sipe bottom point and a sipe top point at the average sipe line. A sipe inclination line extends from the sipe bottom point to the sipe top point, and a reference line extends through the sipe bottom point. A sipe inclination angle is defined by the reference line and the sipe inclination line and is greater than 0 degrees.
本发明提供了一种重型卡车轮胎胎面,其具有胎肩边缘、胎肩花纹沟和在其间的胎肩花纹条。多个刀槽花纹在胎肩花纹条中,并且相对于侧向方向的取向小于20度。刀槽花纹在纵向方向上彼此间隔5至18毫米。附加地或可替代地,刀槽花纹被布置成使得参考平面延伸通过平均刀槽花纹线处的刀槽花纹底部点和刀槽花纹顶部点。刀槽花纹倾斜线从刀槽花纹底部点延伸到刀槽花纹顶部点,参考线延伸穿过刀槽花纹底部点。刀槽花纹倾斜角由参考线和刀槽花纹倾斜线限定,并且大于0度。
