[0002] Tires are the running structure of a car. They can transmit the driving, steering and braking forces of the car to the ground, thereby realizing the car's driving, traction, braking and steering functions, allowing the car to run normally on the road.

[0003] SUV is a common type of vehicle. The tires used for SUV are special compared to those for other types of vehicles. The tire patterns of SUV are generally designed with deeper and more grooves to improve the tire's grip and meet the off-road performance of SUV.

[0004] However, the inventor believes that even if a deeper tread with more grooves is designed, some SUV tires may still have insufficient grip on icy and snowy roads, affecting the safe driving of the vehicle; therefore, how to solve the above technical problems and design an SUV tire pattern structure with better grip is a technical problem that needs to be solved in the current field of tire technology.

[0005] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art.

[0030] In view of the problems mentioned in the above background technology, the embodiment of the utility model provides a high-grip SUV tire pattern and tire to solve the above technical problems, and its technical solution is as follows:

[0031] A high-grip SUV tire pattern, comprising:

[0032] A plurality of unequal pitch pattern blocks extending in the circumferential direction of the tread; each pitch pattern block includes a middle pattern block 11, and a middle rib pattern block 12 and a shoulder pattern block 13 located on both sides of the middle pattern block 11 and distributed in sequence;

[0033] A middle longitudinal main groove 1 is provided between adjacent middle pattern blocks 11 and middle rib pattern blocks 12, and a shoulder longitudinal main groove 2 is provided between adjacent middle rib pattern blocks 12 and shoulder pattern blocks 13;

[0034] The middle pattern block 11 of each pitch is provided with two central short grooves 3 which are centrally symmetrical to each other, two central oblique short fine grooves 4 which are centrally symmetrical to each other, and one central fine groove 5;

[0035] The outer end of the central short groove 3 is connected to the adjacent middle longitudinal main groove 1, and the two centrally symmetrical central short grooves 3 are connected through the central fine groove 5;

[0036] The central oblique short fine groove 4 is spaced apart from the central short groove 3 , and the outer end of the central oblique short fine groove 4 is connected to the adjacent middle longitudinal main groove 1 .

[0037] The design of the central oblique short fine groove 4 and the central fine groove 5 can divide the middle pattern block 11, making the tread softer, allowing the tread to contact the road surface more fully, and enhancing the tire's grip on various road conditions, especially wet and slippery roads.

[0038] It should be noted that the directional word "longitudinal" refers to the direction in which the tire rolls; the directional word "lateral" refers to the direction perpendicular to the mid-plane of the tire.

[0039] In the present embodiment, a middle rib transverse groove 6 and a plurality of middle rib corrugated fine grooves 8 are arranged at intervals along the circumferential direction of the tread on the middle rib pattern block 12 of each pitch; specifically, 1-3 middle rib corrugated fine grooves 8 are arranged at intervals; wherein, the middle rib transverse groove 6 and the middle rib corrugated fine groove 8 are connected to the shoulder longitudinal main groove 2 and the middle longitudinal main groove 1 on both sides, respectively.

[0040] The obliquely designed mid-rib transverse groove 6 makes the load transfer on the tread smoother, reduces the vibration and impact when entering the contact area, and makes the air release smoother when leaving the contact area;

[0041] The design of the corrugated fine groove 8 in the middle rib softens the tread, which can make the tread contact with the road surface more fully, enhance the grip of the tire on various road conditions, especially on wet and slippery roads, and enhance the grip of the tire on icy and snowy roads.

[0042] In this embodiment, the side of the middle rib transverse groove 6 close to the center line is a straight groove, and the angle α with the center line is 50-80°; the side of the middle rib transverse groove 6 away from the center line is an arc groove tangent to the straight groove connected thereto.

[0043] In this embodiment, a shoulder transverse groove 10 and a plurality of shoulder wave-shaped fine grooves 9 are arranged at intervals along the circumferential direction of the tread on the shoulder pattern block 13 of each pitch;

[0044] The shoulder transverse grooves 10 make the load transfer on the tread smoother, reduce the vibration and impact when entering the contact area, and make the air release smoother when leaving the contact area;

[0045] The design of the shoulder wave-shaped fine groove 9 makes the tread softer, which can make the tread contact with the road surface more fully, enhance the grip of the tire on various road conditions, especially wet and slippery roads, and enhance the grip of the tire on icy and snowy roads.

[0046] Specifically, the shoulder corrugated fine grooves 9 are arranged at intervals of 1-3; the lengths of these shoulder corrugated fine grooves 9 can be different, and the design of replacing the wider groove with a narrow groove reduces pump noise and impact noise, thereby reducing driving noise.

[0047] In this embodiment, the outer end of the shoulder transverse groove 10 is enlarged to form a shovel shape; a shoulder notch 11 is provided near the enlarged portion of the outer end of the shoulder transverse groove 10; the outer end of the shoulder transverse groove 10 is enlarged to form a shovel shape and the shoulder notch 11 design enhances the vehicle's grip on muddy roads.

[0048] In this embodiment, the width of the shoulder wave-shaped narrow groove 10a is 0.4-1.0 mm.

[0049] Preferably, a shoulder shallow groove 7 is provided between the shoulder pattern block 13 and the shoulder longitudinal main groove 2; the distance between the shoulder shallow groove 7 and the shoulder longitudinal main groove 2 is 5-8 mm.

[0050] A tire comprises a tread that contacts the ground during driving, wherein the tread is provided with the high-grip SUV tire pattern as described above.

[0051] The device embodiments described above are merely illustrative, wherein the units described as separate components may or may not be physically separated, and the components shown as units may or may not be physical units, and may be located in one place or distributed over multiple network units. Some or all of the modules may be selected according to actual needs to achieve the purpose of the solution of this embodiment.
