Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

It should be noted that the term "circumferential direction" as used herein refers to a direction along the circumferential surface of the tire, and is a vertical direction in the plane of fig. 1. "axial" means a direction parallel to the axis of rotation of the tire, and is horizontal in the plane of FIG. 1. "radial direction" means a radial direction from the tire rotation axis to the tire circumferential surface, and is a direction perpendicular to the paper surface in the plane of fig. 1. "the center position of the crown" refers to the circumferential center axis position of the tire, or referred to as the tire equator. Herein, the direction of the central position axially close to the crown is called the axial inner side, and the direction of the central position axially far from the crown is called the axial outer side; the direction radially closer to the axis of rotation of the tire is referred to as the radially inner side, and the direction radially farther from the axis of rotation of the tire is referred to as the radially outer side. References herein to "upper", "lower", "left" and "right" are relative to the orientation shown in fig. 1. The "tread" referred to herein is the surface of the tire that contacts the ground during driving, including the crown in the middle and the shoulders on both sides.

Fig. 1 to 3 show one embodiment of a pneumatic tire for a vehicle according to the present invention. The pneumatic tire for a vehicle includes a tire body 1. Two steel wire rings 13 are symmetrically and fixedly connected with two ends of the inner part of the tyre body 1.

Two first drainage grooves 2 which continuously extend along the circumferential direction are symmetrically arranged on the left and right of the tread corresponding to the center of the tread, and a second drainage groove 3 which continuously extends along the circumferential direction is arranged between the two first drainage grooves 2. In this embodiment, the second drain gutter 3 is located at the very center of the crown. On the axially outer side of the first drain groove 2, there are also provided two circumferentially continuously extending third drain grooves 5 which are bilaterally symmetrical with respect to the center position of the crown, i.e., in this embodiment, with respect to the second drain groove 3. The first drain groove 2, the second drain groove 3, and the third drain groove 5 constitute a main drain groove of the tire tread for quickly draining water between the tire and the ground.

Preferably, the two first drain grooves 2 and the two third drain grooves 5 are gradually widened from the groove bottom to the notch, as shown in fig. 3. This facilitates rapid drainage of water and other foreign matter from the trench.

The second drainage groove 3 and the first drainage grooves 2 on the left and right sides thereof divide the crown of the tire body 1 into two support blocks 4 extending in the circumferential direction. A plurality of drainage ditches 17 are formed in the upper side wall of the supporting block 4 at intervals along the circumferential direction, and the drainage ditches 17 are respectively communicated to the first drainage grooves 2 at two sides from the second drainage ditch 3 at the center. These axial drains 17 can quickly drain the standing water in the second drain groove 3. In the embodiment shown in fig. 1, the respective drainage gutters 17 extend in a direction from the central second drainage gutter 3 to the first drainage gutters 2 on both sides in a manner of being inclined downward and gradually becoming wider, thereby further facilitating quick drainage.

A plurality of first drain grooves 6 which are spaced in the circumferential direction and communicate the adjacent first drain grooves 2 and third drain grooves 5 are provided between the first drain grooves 2 and the third drain grooves 5 on the same side with respect to the center position of the tire crown. These first drain grooves 6 divide a plurality of functional blocks 7 together with the first drain grooves 2 and the third drain grooves 5 adjacent to each other on the same side. In fig. 1, each first drain tank 6 extends straight, thereby forming a square functional block 7. In other embodiments, the first drain tank 6 may also extend obliquely and/or curvedly.

As is clearly visible in fig. 2, the upper side wall inside the functional block 7 is provided with an annular ring groove 8. Openings 9 are arranged on both sides of the ring groove 8. The ring groove 8 communicates with the first drain groove 2 and the third drain groove 5 through openings 9, respectively. By said arrangement of the first drainage channel 6 and the functional block 7, a quick drainage of water between the tyre and the ground is further facilitated.

As also shown in fig. 2, the opening 9 and the ring groove 8 define an arc-shaped block 10 inside the functional block 7. The left and right side walls of the arc block 10 are respectively provided with a closed groove 15 which are concave in opposite directions. The end of the closed slot 15 facing the inside of the arc-shaped block 10 is closed, and the end far away from the inside of the arc-shaped block 10 is open.

In a preferred embodiment, the closed slot 15 widens progressively in the direction from the closed end towards the open end, and the open end is aligned with the position of the opening 9, as shown in fig. 2. It is also preferred that the functional block 7 is provided with notches 14 at each of the four corners. The recess 14 is recessed from the corner side wall of the functional block 7 in the direction of the arc-shaped block 10. The notch 14 and the closed groove 15 respectively reduce the strength of the functional block 7 and the arc-shaped block 10, improve the wear resistance between the functional block 7 and the arc-shaped block 10, and further improve the ground gripping performance of the tire.

The axial outer side groove wall of the third drainage groove 5 is provided with a plurality of second drainage grooves 11 communicated to the outer side tire shoulder. The second drainage channel 11 and the third drainage channel 5 thus divide the crown into a plurality of lateral cleats 12. The second drain groove 11 can quickly drain the accumulated water in the third drain groove 5. The upper side wall of the side anti-skid block 12 is provided with a groove 16 and a plurality of anti-skid lines 18 which are spaced along the circumferential direction. The grooves 16 reduce the strength of the side anti-skid blocks 12 and improve the wear resistance; the anti-skid threads 18 increase the friction of the side anti-skid blocks 12, thereby further improving the anti-skid performance of the tire.

The recess 16 may have any shape. Preferably, the recess 16 is oval, for example with the major axis oriented axially, circumferentially or obliquely. It is further preferred that the major axis of the ellipse extends in the axial direction of the tire, as shown in fig. 1. The oval shape provides good tension and is particularly advantageous in reducing the strength of the side cleats 12.

The second water discharge groove 11 may have an extended shape of a wave, a straight line, a curved line, etc. Preferably, the second water discharge channel 11 passes at least partially through the non-slip thread 18, as shown in fig. 1. It is also preferred that the non-slip threads 18 are wavy or extending in a zigzag pattern to increase the friction effect.

Further, the second drain groove 11 is preferably inclined downward from the third drain groove 5 toward the shoulder on the same side. As shown in fig. 1, the second drain groove 11 extends downward in a wave shape from the third drain groove 5 to the outer shoulder.

In some preferred embodiments, the tire body 1 has a flexible graphite rubber layer (not shown) compounded on the crown. The wear resistance of the flexible graphite rubber layer is 10 to 15 times that of a common rubber tire, so that the wear resistance and the service life of the tire are greatly improved, and the use cost of a vehicle is reduced.

According to the utility model discloses a tire is when using, through the first drainage groove 2 that sets up, second drainage groove 3, supporting shoe 4, third drainage groove 5, first drainage groove 6, function block 7, arc piece 10, second drainage groove 11 and side non slipping spur 12, can go in the rainy day, discharge the water between tire and the ground fast, avoid because ponding is more causes the vehicle to sideslip easily between tire and the ground and tumble, give people the problem that the security of lives and property brought the hidden danger.
