The present invention relates to the technical field of tires, and especially relates to an electric vehicle tire sheet steel and an electric vehicle tire. The 3D steel sheet of the electric vehicle tire is disclosed. An oblong groove is formed in the front side of the steel sheet, the part, where the groove is located, of the steel sheet is in the shape of an S-shaped curved face in the length direction, and the two ends of the steel sheet are parallel to each other. The 3D steel sheet of the electric vehicle tire has the unique S-shaped curved face groove structure, self-kneading designed tread patterns can be manufactured by combining a tire production die for use, and front-back adjacent 3D pattern blocks are deformed to quickly make contact with each other under the effect of friction force between the tire and the ground, so that the gripping performance is better provided. During running at corners, especially at fast turning, the pattern blocks adopting the self-kneading design are adopted, and the two pattern blocks in the front-back pitch are kneaded together, so that the lateral gripping performance is improved. Bulges are designed on the vertical faces of the pattern blocks of the 3D steel sheet, to make a faster response to the function, so that the good lateral grip performance is provided for the fast turning of the vehicle.
