High grip snow tire

A high grip snow tire, comprising:

• a tread, wherein pattern blocks and friction blocks are provided on a circumferential surface of the tread and positioned on a same side with an equatorial plane of the tread;
• the pattern blocks and the friction blocks are successively distributed along a circumference of the tread, and the pattern blocks and the friction blocks are in mirror symmetry about the equatorial plane;
• each of the friction blocks comprises a plurality of fixing protrusions, which are gradually sharp along a direction away from the tread;
• a surface of the tread is provided with a protection groove, and the plurality of fixing protrusions are positioned in the protection groove;
• each of the pattern blocks comprises a first pattern block, a second pattern block and a third pattern block, which are all in fixed connection with the tread, wherein the first pattern block, the second pattern block and the third pattern block are gradually away from the equatorial plane of the tread in a direction against a running direction;
• each of the pattern blocks also comprises a fourth pattern block, a fifth pattern block and a sixth pattern block, wherein the fourth pattern block is positioned on a side of the first pattern block against the running direction, and the fifth pattern block and the sixth pattern block are successively distributed away from the fourth pattern block in the direction against the running direction,
• wherein a fifth groove parallel to the equatorial plane of the tread is formed on a surface of the sixth pattern block away from the tread, the fifth groove penetrates through the sixth pattern block, and the sixth pattern block is provided with a water accommodation groove, which is positioned in a middle of the fifth groove and crosses the fifth groove.
