With the development of new energy electric vehicles, it has also driven the development of the supporting tire industry for new energy electric vehicles. At present, many countries and regions have begun to promote new energy electric vehicles to reduce the pollution caused by automobile exhaust to the environment, which provides a broad market space for the new energy electric vehicle tire industry. The new energy electric vehicle market is booming. Tires are one of the core components of automobiles and are essential consumables for new energy electric vehicles. Coupled with long-term wear, traffic accidents, damage from sharp instruments and other reasons, it is necessary to update tires, and choosing a good and suitable tire should not be underestimated.

DETAILED DESCRIPTION
[0021] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete and to fully convey the concepts of example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their repeated description will be omitted.
[0022] The words expressing positions and directions described in the present utility model are all explained by taking the drawings as examples, but they can be changed as needed, and all the changes are included in the protection scope of the present utility model.
[0023] Reference Figure 1-2 The utility model provides an ultra-high performance EV radial tire, with the middle line of the tread 1 as the equator, one side as the inner side of the tire, the other side as the outer side of the tire, and the direction from the inner side of the tire to the outer side as the width direction, including: a central continuous pattern block 2 arranged along the equator, the central continuous pattern block 2 is continuous on the tread 1, and the central continuous pattern block 2 includes a plurality of connecting ribs 11 inclined at an angle of 28 degrees to the width direction. It also includes an inner pattern block 10 and an inner shoulder block 9 near the inner side of the central continuous pattern block 2, and an outer pattern block 8 and an outer shoulder block 7 near the outer side of the central continuous pattern block 2, wherein the outer shoulder block 7 and the outer pattern block 8 are separated by a first spacing groove 3, the outer pattern block 8 and the central continuous pattern block 2 are separated by a second spacing groove 4, the central continuous pattern block 2 and the inner pattern block 10 are separated by a third spacing groove 5, and the inner pattern block 10 and the inner shoulder block 9 are separated by a fourth spacing groove 6. The three-plus-one groove combination is used, which is conducive to wetland drainage and reducing air compression frequency, reducing noise, and the outer fine grooves merge into the shoulder to form a large rigid pattern, which is conducive to ground grip and improves high-speed performance, making electric vehicles safer, more comfortable and easier to control on urban roads.
[0024] In one embodiment, the width ratio of the first spacing groove 3, the second spacing groove 4, the third spacing groove 5 and the fourth spacing groove 6 is 7:16:15:13. According to experimental verification, within this ratio range, the inner shoulder block 9 located on the inner side can effectively grip the ground and improve the tire performance at high speed. The three wider grooves can also help to drain water from wetlands, reduce air compression frequency, and reduce noise.
[0025] The four straight groove continuous patterns, combined with a simple and smooth pattern design, can reduce the tread creep and deformation hysteresis loss of the tire during high-speed driving, thereby reducing rolling resistance. For EV electric vehicles, it can greatly save electricity and increase mileage.
[0026] In one embodiment, the inner pattern and the outer pattern block 8 are asymmetrical about the equator, and the inner shoulder block 9 and the outer shoulder block 7 are asymmetrically arranged about the equator. Suitable for high-speed driving, the pattern orientation is the same and asymmetrical, which can provide better stability and grip.
[0027] In one embodiment, at least one steel plate pattern is formed on every two of the central continuous pattern blocks 2. The high-speed gripping ability and quietness are improved. Since smooth patterns are prone to partial wear in the later period of use on urban roads, non-penetrating steel plate patterns can reduce the loss of the car during long-term driving.
[0028] In one embodiment, a drainage groove 12 connected to the first spacing groove 3 is formed on the outer shoulder block 7, and in the width direction, the drainage groove 12 does not penetrate the outer shoulder block 7. The drainage groove 12 on the outer shoulder block 7 can be connected to the first spacing groove 3. When driving at high speed, the first spacing groove 3 and the drainage groove 12 cooperate to quickly drain water under the tread 1 to maintain stability.
[0029] In one embodiment, the outer shoulder block 7 is further provided with a steel plate pattern spaced apart from the drainage groove 12. The pattern noise is reduced and the riding comfort is improved, while the grip is improved.
[0030] In one embodiment, the inner shoulder block 9 is provided with a guide pattern 13, and the guide pattern 13 is not connected to the fourth spacing groove 6. The inner guide pattern 13 is not connected to the fourth spacing groove 6, which can reduce the tread noise and improve the riding comfort.
[0031] Although the embodiments of the utility model have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the utility model. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the utility model without departing from the principles and purpose of the utility model. All of these changes should fall within the scope of protection of the claims of the utility model.
