The pneumatic tire tread structure for the electric motorcycle comprises a tread pattern, the tread pattern is composed of a plurality of pattern main groove sets, the pattern main groove sets are distributed on the two sides of the center line of the tread in the circumferential direction, and the adjacent pattern main groove sets located on the two sides of the center line of the tread are arranged in a staggered mode; the main pattern grooves of each main pattern groove group are distributed in a step shape from the axial inner side to the axial outer side, the tire tread is sequentially divided into a central area, a middle area and a tire shoulder area from the center line of the tire tread to the two axial sides, and the main pattern grooves are formed in the central area, the middle area and the tire shoulder area respectively; the pattern main groove is composed of a first pattern groove and a second pattern groove, the first pattern groove is circumferentially parallel to the center line of the tread, and the second pattern groove is connected with the first pattern groove and faces the center line of the tread. According to the invention, the rolling resistance performance and the wet ground gripping performance of the tread tire can be considered, and the abnormal abrasion phenomenon of the tire is avoided.
本发明公开一种电动摩托车用充气轮胎胎面结构,包括胎面花纹,胎面花纹由多个花纹主沟组组成,花纹主沟组沿周向分布于胎面中心线两侧,位于胎面中心线两侧相邻的花纹主沟组交错排布;每一花纹主沟组的花纹主沟从轴向内侧往外侧呈阶梯状分布,轮胎胎面由胎面中心线往轴向两侧依次区分为中央区域、中间区域和胎肩区域,中央区域、中间区域和胎肩区域分别设有花纹主沟;花纹主沟由第一花纹沟和第二花纹沟组成,第一花纹沟与胎面中心线周向平行,第二花纹沟与第一花纹沟连接并朝向胎面中心线。本发明可以兼顾胎面轮胎滚阻性能和湿地抓地性能,同时避免轮胎出现异常磨耗现象。
