The invention discloses an all-steel radial tire with low rolling resistance and high wet grabbing, the all-steel radial tire is provided with a tread, the tread is provided with five circumferential grooves extending along the circumferential direction of the tire, one central pattern groove and two shoulder pattern grooves are open type pattern grooves, and the other central pattern groove and the other two shoulder pattern grooves are open type pattern grooves. The two 3D grooves close to the central pattern groove are self-closed in a loading state; the five circumferential grooves divide the tread into six pattern blocks, the widths of the six pattern blocks are respectively A, B, C, D, E and F in sequence along the width direction of the tread, and meet the following relations: A = F, B = E, C = D, A: B: C = (1.51 +/-3%): (1.04 +/-3%): (1 +/-3%), 0.15 < = A/L < = 0.25, and L is the tread arc length of the tread along the width direction of the tire. According to the invention, the tire structure, the pattern style and the tire formula are optimized, so that the tire has low rolling resistance and high wet grabbing performance, and the shoulder eccentric wear prevention performance and the tire conductivity are both considered.

    本发明公开一种低滚阻高湿抓的全钢子午线轮胎,具备胎面,所述胎面上开设有沿轮胎圆周方向延伸的周向沟槽,所述周向沟槽设置有五条,一条所述中央花纹沟和两条所述肩部花纹沟为开放式花纹沟槽,两条靠近中央花纹沟为加载状态自闭合的3D沟槽;五条所述周向沟槽将所述胎面划分成六个花纹块,六个所述花纹块的宽度沿所述胎面的宽度方向依次分别为A、B、C、D、E、F,且满足如下关系A=F、B=E、C=D,A:B:C=(1.51±3%):(1.04±3%):(1±3%),0.15≤A/L≤0.25,其中L为所述胎面沿轮胎宽度方向的胎面弧长。本发明通过对轮胎结构、花纹样式和轮胎配方三方面进行优化,实现轮胎具有低滚阻和高湿抓性能,并兼顾防肩部偏磨性能和轮胎导电性能。
