[0028] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0029] In one embodiment, Figure 1-Figure 10 As shown, an SUV tire with good noise performance comprises a central land portion 1, an outer auxiliary side land portion 2 and an inner auxiliary side land portion 4, an outer side land portion 3 and an inner side land portion 5, a circumferential main groove 6, and a circumferential auxiliary groove 7. The central land portion 1, the outer auxiliary side land portion 2 and the inner auxiliary side land portion 4, the outer side land portion 3 and the inner side land portion 5 are arranged along the circumferential direction, and the inner side land portion 5 extends along the circumferential direction of the outer surface of the tread. The central land portion 1 is located between two circumferential main grooves 6 on the tire surface, and two circumferential auxiliary grooves 7 are located outside the two circumferential main grooves 6. The outer auxiliary side land portion 2 and the inner auxiliary side land portion 4 are located between the adjacent circumferential main grooves 6 and circumferential auxiliary grooves 7 on the tire surface, and the outer side land portion 3 and the inner side land portion 5 are located outside the circumferential auxiliary groove 7.

[0033] In one embodiment, Figure 1 As shown, each outer side land portion 3 has a plurality of outer side land portion main grooves 12 and a plurality of outer side land portion secondary grooves 13 , and each inner side land portion 5 has a plurality of inner side land portion main grooves 15 and an inner side land portion secondary grooves 16 .

[0034] In one embodiment, Figure 1 and Figure 4 As shown, the outer side land portion main cutting groove 12 extends to the shoulder, and the widths of multiple outer side land portion main cutting grooves 12 are different according to different pitches and are arranged along the circumferential direction. They are arranged at various unequal pitches on the central land portion, the secondary portion, and the shoulder. After adopting such a structure, a variety of variable pitch designs can effectively reduce the pattern noise of the tire during driving.

[0035] The above embodiment discloses an SUV tire with good noise performance, wherein a plurality of short grooves are arranged at various unequal pitches on the central land portion, the secondary portion, and the shoulder portion. After adopting such a structure, a plurality of variable pitch designs, unequal circumferential main grooves, and circumferential secondary groove depth and width designs are designed to improve the noise performance of the tire pattern when driving on the road, and the multi-pitch arrangement can effectively reduce the pattern noise of the tire during driving.
