Referring to fig. 1-3, a safe and energy-saving electric motorcycle tire comprises a tire body 1, wherein a ply, an inner liner and bead wires are sequentially arranged in the tire body 1, an outer ring of the tire body 1 is a tire crown 2, the direction from the outer ring to the inner ring of the tire body 1 is sequentially a tire shoulder 3, a tire side 4 and a toe opening 5, patterns are arranged on the tire crown 2, the patterns comprise a plurality of first grooves 21, second grooves 22 and third grooves 23, two ends of the first grooves 21 are respectively positioned at two sides of the tire crown 2, and the first grooves 21 are alternately distributed along the circumferential direction of the tire crown 2 in a horizontal mirror image mode; a second groove 22 and a third groove 23 are further arranged between the two adjacent first grooves 21.

Here, the tire width 165, the percentage of the tire cross-sectional height to the width of 45%, and the rim diameter of 12 inches were used in the present embodiment, but the range of application of the pattern structure in the present embodiment is not limited to the tire of this parameter.

Under this design, the arrangement mode that the first slot 21 adopts along the circumference mirror image alternate distribution of crown 2 for first slot 21 does not have the symmetry on crown 2, and the decorative pattern that adopts this kind of mode to arrange can provide gripping and motion performance for the tire, and this decorative pattern design still provides super wide driving face for the tire, has increased the area of ground contact of tire, makes the tire travel more steady safety, because the decorative pattern and the tire rotation direction of this tire unanimity, can less decorative pattern's rolling resistance, thereby more energy-conserving when electric motorcycle car is traveling.

The first grooves 21 have drainage performance at both ends of the crown 2, respectively, and the second grooves 22 and the third grooves 23 provided between the adjacent two first grooves 21 can further provide grip of the tire.

Preferably, the first groove 21 includes a Y-shaped portion 211 and a V-shaped portion 212, in which two upper ends and one lower end are respectively included, wherein one end of the upper end of the Y-shaped portion 211 is located at one side of the crown 2, the other end of the upper end of the Y-shaped portion 211 is connected with one end of the upper end of the V-shaped portion 212, the lower end of the V-shaped portion 212 is located at the other side of the crown 2, and the opening of the V-shaped portion 212 faces the Y-shaped portion 211, and the first groove 21 is folded several times from one side to the other side of the crown 2, in such a manner that the grip of the tire can be ensured.

Further, we found that if only the first grooves 21 are used, the blank area between two adjacent first grooves 21 is relatively large, and there is a risk of slipping through the blank area when the vehicle is running on wet ground, so that the second grooves 22 with V-shaped structures and the third grooves 23 with bar-shaped structures are added between two adjacent first grooves 21, the second grooves 22 are located below the V-shaped portions 212 of the first grooves 21, the third grooves 23 are located below the Y-shaped portions 211 of the first grooves 21, after the first grooves 21 are alternately distributed in mirror images, the second grooves 22 are changed in position along with the change in position of the V-shaped portions 212 of the first grooves 21, and the third grooves 23 are also changed in position along with the change in position of the Y-shaped portions 211 of the first grooves 21.

Preferably, the first grooves 21, the second grooves 22 and the third grooves 23 are arranged at equal intervals.
