It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

As shown in fig. 1 and 2, a tire tread pattern capable of improving performance on ice and snow includes a circumferential groove and a circumferential block. The circumferential pattern blocks are provided with pattern grooves. Separating the circumferential pattern blocks by circumferential pattern grooves; the circumferential blocks include shoulder blocks 1, intermediate blocks 2, and other blocks 3 between the shoulder blocks and the intermediate blocks.

The lug groove on the shoulder pattern block 1 is an oblique lug groove A8, the length of the oblique lug groove A: width: the depth ratio is 10-100: 1: 1, the inclined angle alpha of the oblique lug groove A relative to the transverse direction is 30-60 degrees. By controlling the width, depth and length ratio of the oblique pattern groove A, ice/snow is not easy to remain in the groove, and the grip effect of the oblique pattern groove A on the shoulder pattern blocks 1 is enhanced. And the proportional design has little influence on the oil saving performance, and ice/snow at the bottom of the ditch is obviously removed, so that the ground grabbing function under the ice/snow road surface is realized, and the problem of contradiction between the ground grabbing force on the ice/snow road surface and the oil saving performance design is solved.

The pattern groove of the middle pattern block 2 is a pattern groove C9, and the ratio of the width to the depth of the pattern groove C is 0.8-1.2. By controlling the width and depth ratio of the C9, ice/snow is not easily retained in the groove, and the grip of the C9 on the middle block 2 is enhanced. And the proportional design has little influence on the oil saving performance, and ice/snow at the bottom of the ditch is obviously removed, so that the ground grabbing function under the ice/snow road surface is realized, and the problem of contradiction between the ground grabbing force on the ice/snow road surface and the oil saving performance design is solved.

The other blocks 3 between the shoulder block 1 and the middle block 2 are provided with oblique rib grooves B10, the length of the oblique rib groove B10: the width ratio is 10-100: 1, the oblique angle beta of the oblique lug grooves B10 relative to the transverse direction is 30-60 degrees. By controlling the ratio of the width to the length of the oblique lug groove B10, ice/snow is less likely to remain in the groove, enhancing the grip of the oblique lug groove B10 on other blocks 3. And the proportional design has little influence on the oil saving performance, and ice/snow at the bottom of the ditch is obviously removed, so that the ground grabbing function under the ice/snow road surface is realized, and the problem of contradiction between the ground grabbing force on the ice/snow road surface and the oil saving performance design is solved.

Slant checkered groove A's both ends along length direction, one end are the arc end, and one end is most advanced I, and on tire tread plane, the contained angle of most advanced I is 30~ 60. This is done to balance the lateral stiffness with the longitudinal stiffness.

The shape of the oblique lug groove A can also be a quadrangle.

The oblique pattern grooves A on the circumferential pattern blocks on the two sides are oppositely arranged, and the oblique pattern grooves A on the circumferential pattern blocks on the two sides are centrosymmetric. The purpose of this arrangement is to ensure that the tread has uniform rigidity and beautiful appearance.

In addition, the middle part of the oblique pattern groove B10 is deeper than the two ends, so that the tire has low-frequency creeping effect in the running process, and ice/snow is further not easy to remain in the groove.

The area occupied by the deeper part of the middle part of the oblique decorative pattern groove B is less than or equal to 1/3 of the total area of the oblique decorative pattern groove B, so that ice/snow is further not easy to remain in the groove.

The oblique rib grooves B10 penetrate the other blocks 3 in the width direction and connect with the circumferential grooves on both sides of the other blocks 3. The purpose of this arrangement is to facilitate smooth discharge of the snow and ice pushed in by the oblique lug grooves B10 when the tire is running.

As shown in fig. 1 and fig. 2, the lug groove C9 comprises a short transverse groove and an oblique groove communicated with the short transverse groove, one end of the oblique groove and one end of the short transverse groove are thick ends, the other end of the oblique groove is a tip end ii, and the included angle of the tip end ii on the plane of the tire tread is 10-15 degrees. This is done to avoid angular coincidence with B10.

The lug groove C may be polygonal.

The pattern grooves C are positioned at the joints of the middle pattern blocks and the circumferential pattern grooves at the two sides of the middle pattern blocks, and the pattern grooves C at the two side parts of the middle pattern blocks are arranged at intervals, as shown in FIG. 1 and FIG. 2, the transverse short grooves of the pattern groove C9 are connected with the circumferential pattern grooves at the two sides of the middle pattern blocks; and the pattern grooves C on the two side parts of the middle pattern block are centrosymmetric. The purpose of this arrangement is in order to guarantee that the tread rigidity is even, the outward appearance is pleasing to the eye.

Here illustrated by way of example in the accompanying drawings: the circumferential pattern grooves are six, the circumferential pattern blocks are seven, and 80% -90% of the ground contact area is ensured except for the conventional design; so that the shoulder blocks 1 are two, the middle block 2 is one, and the other blocks 3 are four.

The circumferential groove between the shoulder pattern block 1 and the adjacent other pattern blocks 3 is a circumferential groove I4, the circumferential groove between the middle pattern block 2 and the adjacent other pattern blocks 3 is a circumferential groove II 5, and the circumferential groove between the adjacent other pattern blocks 3 is a circumferential groove III 6.

The circumferential grooves I4 are of conventional design. On the basis of conventional design, the ratio of the width to the depth of the circumferential pattern groove II 5 and the circumferential pattern groove III 6 is controlled within the range of 0.1-0.3, in addition, transverse grooves 7 are arranged at intervals on two sides of each circumferential pattern groove II 5 and each circumferential pattern groove III 6, and the transverse grooves 7 extend to the circumferential pattern blocks on the two sides; the ratio of the length of the transverse groove 7 to the width of the circumferential groove to which it is connected is 1/2-1, the length of the transverse groove 7: width: the ratio between the depths is not limited as long as the use of the tire is not affected. The communication of the lateral grooves 7 with the oblique rib grooves B10 connects the oblique rib grooves B10 with the circumferential groove.
