The invention relates to the technical field of tire production, and particularly discloses a new energy tire pattern structure and a tire, the new energy tire pattern structure comprises a longitudinal groove, a transverse groove and a tire steel sheet which are arranged on a tire body; the longitudinal grooves are distributed in the axial direction of the tire and located in the middle of the tread of the tire body, the transverse grooves are formed in the positions, close to the edges of the two sides of the tread, of the tire body, and the tire steel sheets are distributed among the multiple longitudinal grooves. The middle part adopts a steel sheet design to balance the pattern rigidity, increase the grounding area and improve the tire abrasion performance; the wet land is used for breaking a water film, so that the road holding force of the tire is improved; no steel sheet is designed between the shoulder transverse grooves of the tire body, so that the rigidity of the pattern blocks is increased, the instantaneous holding power is improved, and the instantaneous torque of a new energy automobile is dealt with; when the new energy tire patterns are arranged at all pitches in the circumferential direction of the tread, a multi-layer variable-pitch arrangement mode is adopted, and the low-noise characteristic of the tire is achieved through analogue simulation optimization analysis.
