Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The utility model provides a cross country vehicle tire pattern and a tire, which can effectively improve the trafficability, high speed and wear resistance of the tire by reasonably designing the tire pattern.

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.

As shown in FIG. 1, the utility model provides a cross-country vehicle tire pattern, which comprises a first pattern block 1, a second pattern block 2, a third pattern block 3 and a fourth pattern block 4 which are arranged on a tire tread, wherein the sum of the areas of the first pattern block 1, the second pattern block 2, the third pattern block 3 and the fourth pattern block 4 accounts for 55-65% of the area of a crown driving surface, and the first pattern block 1, the second pattern block 2, the third pattern block 3 and the fourth pattern block 4 are arranged in a zigzag manner in the horizontal direction of the tire tread. The stable undirected large pattern blocks can provide strong ground gripping performance and wear resistance, greatly reduce the damage to the soft-base pavement and ensure high passing performance when the non-paved pavement runs.

Specifically, in order to improve the mud throwing performance of the tire, the extending positions of the first pattern blocks 1 and the fourth pattern blocks 4 towards the tire shoulders are open 5, which is beneficial to throwing mud from the tire tread.

Specifically, a concave groove 6 is arranged at the outer shoulder of the first pattern block 1; and the external shoulder of the fourth pattern block 4 is provided with a raised pattern 7.
