The invention provides a tire tread structure which comprises a plurality of longitudinal grooves extending in the circumferential direction of a tire, and the longitudinal grooves are formed in the width direction of the tire at intervals so as to divide a tire tread of the tire into two tire shoulder pattern parts and a middle pattern part located between the two tire shoulder pattern parts. The first communicating groove is formed in the middle pattern part and is used for communicating two adjacent longitudinal grooves; wherein the number of the first communicating grooves is multiple, the multiple first communicating grooves are formed in the circumferential direction of the tire at intervals so as to divide the middle pattern part into multiple middle pattern blocks, at least part of the middle pattern blocks are located in a wear heat generation area of the tire, the wear heat generation area has the area S1, and the middle pattern blocks located in the wear heat generation area have the area S2; the area S1 and the area S2 meet the condition that 0.75 S1 < = S2 < = 0.85 S2. The mining dump truck tire effectively solves the problem that a mining dump truck tire in the prior art cannot give consideration to the control performance, the heat dissipation performance, the wear resistance and the cutting resistance at the same time.
本发明提供了一种轮胎胎面结构,包括多个延轮胎的周向延伸的纵向沟槽,多个纵向沟槽沿轮胎的宽度方向间隔设置,以将轮胎的胎面分隔为两个胎肩花纹部和位于两个胎肩花纹部之间的中间花纹部;第一连通沟槽设置在中间花纹部上,以用于连通相邻的两个纵向沟槽;其中,第一连通沟槽为多个,多个第一连通沟槽沿轮胎的周向间隔设置,以将中间花纹部分隔为多个中间花纹块,至少部分中间花纹块位于轮胎的磨损生热区域内,磨损生热区域具有面积S1,位于磨损生热区域内的中间花纹块具有面积S2,面积S1和面积S2之间满足:0.75S1≤S2≤0.85S2。本发明有效地解决了现有技术中的矿用自卸车轮胎无法兼顾操控性能、散热性能及耐磨、耐切割性能的问题。
