The invention discloses a novel low-rolling-resistance environment-friendly electromobile tire tread structure, wherein a tire adopts a major diameter narrow tread design, and tread groove curves formed by longitudinal grooves, transverse grooves and a main pattern are distributed on the tread of the tire, the longitudinal grooves are divided into a first longitudinal groove, a second longitudinal groove and a third longitudinal groove which are distributed at the center of the thread and are in contact with the ground; the transverse grooves are distributed at the two sides of the first longitudinal groove and the third longitudinal groove and transit to the position of a tire shoulder, and the transverse grooves at the two sides are respectively communicated with the first longitudinal groove and the third longitudinal groove; a main pattern block is in the shape of a bionic leaf, is located between the second longitudinal groove and the third longitudinal groove, and is communicated with the second longitudinal groove and the third longitudinal groove. According to the tire tread structure, a three-dimensional longitudinal groove design is adopted, and a stepped transverse groove design is matched, so that the appearance is more attractive and the whole rigidity of the pattern block is effectively improved, and excellent road grabbing can be still kept along with the abrasion of pattern; a leaf-like bionics design is adopted, and the concept of saving energy and protecting environment is highlighted.
