Along the axial direction, the second opening has a third length, and the second bottom wall has a fourth length, and the third length is greater than the fourth length.

[0009] By adopting the above technical scheme, along the circumferential direction, two adjacent first convex parts in the first row of first convex parts and the second row of first convex parts form a first trough body with a first opening, and the first length of the first opening is greater than the second length of the first bottom wall. Along the axial direction, the first convex parts in the first row of first convex parts and the two first convex parts in the second row of first convex parts symmetrically arranged in pairs form a second trough body with a second opening, and the third length of the second opening is greater than the fourth length of the second bottom wall. That is, the first trough body is narrow at the bottom and wide at the top, and the second trough body is also narrow at the bottom and wide at the top, for example, it can be a trapezoid, a triangle, etc. When the sludge enters the first trough body and the second trough body, the contact area between the bottom of the first trough body and the second trough body and the first convex part is reduced.

[0042] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0043] In some embodiments, see Figure 1 , Figure 2 The present application provides an anti-skid off-road tire, comprising a crown 10, wherein the crown 10 comprises a tread 11. The anti-skid off-road tire provided by the present application further comprises a plurality of rows of first convex portions 2, wherein each row of the first convex portion group 2 comprises a plurality of first convex portions 201, and the plurality of first convex portions 201 are arranged at intervals along the circumferential direction R on the crown 10. Exemplarily, the plurality of rows of first convex portion groups 2 comprise a first row of first convex portion groups 20 and a second row of first convex portion groups 21, wherein the first row of first convex portion groups 20 comprises a plurality of first convex portions 201 arranged at intervals along the circumferential direction R on the crown 10; the second row of first convex portion groups 21 comprises a plurality of first convex portions 201 arranged at intervals along the circumferential direction R on the crown 10, and along the axial direction X, the first row of first convex portion groups 20 and the second row of first convex portion groups 21 are arranged symmetrically in pairs.

[0044] For example, see Figure 3 , Figure 4 , Figure 5 Combined with Figure 1, along the circumferential direction R, two adjacent first protrusions 201 form a first groove body 202 with a first opening 2021, the first groove body 202 includes a first bottom wall 2022, along the circumferential direction R, the first opening 2021 of the first groove body 202 has a first length 11, the first bottom wall 2022 has a second length 12, and the first length 11 is greater than the second length 12; along the axial direction X, the two first protrusions 201 symmetrically arranged in the first row of the first protrusion group 20 and the second row of the first protrusion group 21 form a second groove body 203 with a second opening 2031, the second groove body 203 includes a second bottom wall 2032, along the axial direction X, the second opening 2031 has a third length 13, the second bottom wall 2032 has a fourth length 14, and the third length 13 is greater than the fourth length 14.

[0045] By adopting the above technical solution, along the circumferential direction R, two adjacent first protrusions 201 in the first row of the first protrusion group 20 and the second row of the first protrusion group 21 form a first slot body 202 having a first opening 2021, and the first length 11 of the first opening 2021 is greater than the second length 12 of the first bottom wall 2022. Along the axial direction X, two first protrusions 201 symmetrically arranged in pairs in the first row of the first protrusion group 20 and the second row of the first protrusion group 21 form a second slot body 203 having a second opening 2031, and the third length 13 of the second opening 2031 is greater than the fourth length 14 of the second bottom wall 2032.

[0046] That is, the first trough body 202 and the second trough body 203 are narrow at the bottom and wide at the top (that is, the side away from the tread 11 is narrow, and the side close to the tread 11 is wide), for example, they can be trapezoidal, triangular, etc. When the silt enters the first trough body 202 and the second trough body 203, the contact area between the bottom of the first trough body 202 and the second trough body 203 and the first protrusion 201 is reduced. When disturbed by external force, the silt is easy to fall off from the first trough body 202 and the second trough body 203.

[0047] In some embodiments, see Figure 3 , Figure 4 , Figure 5 Combined with Figure 1 The anti-skid off-road tire includes multiple rows of second convex groups 3, each row of second convex groups 3 includes multiple second convex portions 301, and multiple second convex portions 301 are arranged at intervals on the crown 10 along the circumferential direction R.

Along the circumferential direction R, the third opening 3021 has a fifth length 15 , and the third bottom wall 3022 has a sixth length 16 . The fifth length 15 is greater than the sixth length 16 .

Along the axial direction X, the fourth opening 3031 has a seventh length 17, and the fourth bottom wall 3032 has an eighth length 18, and the seventh length 17 is greater than the eighth length 18. Exemplarily, the fourth groove body 303 and the second groove body 203 intersect and penetrate each other.
