the two sides of each side pattern (20) are respectively a first side and a second side along the circumferential direction of the tire; the end of each side pattern (20) remote from the central pattern (10) is located on a first side of the end thereof close to the central pattern (10); or the end of each side pattern (20) remote from the central pattern (10) is located on a second side of the end thereof close to the central pattern (10);

when each side pattern (20) extends along the corresponding preset curve direction, each side pattern (20) protrudes towards the first side of the side pattern; or each of said side patterns (20) is convex towards its second side.

9. A tyre as claimed in claim 1, wherein each of said side patterns (20) is a rib, each of said side patterns (20) comprising, in the direction of extension of each of said side patterns (20), a first projecting section (21), a second projecting section (22) and a third projecting section (23) connected in succession, the projecting height of said second projecting section (22) being less than the projecting height of said first projecting section (21) and less than the projecting height of said third projecting section (23).

10. The tire according to claim 1,

in each group of the side patterns, a side groove (71) is formed between any two adjacent side patterns (20), each side groove (71) is a strip-shaped groove, and the width of each side groove (71) is gradually increased from one end of each side groove (71) close to the middle pattern (10) to one end of each side groove (71) far away from the middle pattern (10); and/or

The pattern structure further comprises two groups of shoulder pattern groups, and each group of shoulder pattern groups comprises a plurality of shoulder patterns (50) arranged at intervals along the circumferential direction of the tire; the two groups of shoulder pattern groups are respectively arranged on the shoulders (220) at two sides of the tread (210) and are respectively arranged in one-to-one correspondence with the two groups of side pattern groups, so that the shoulder patterns (50) of each group of shoulder pattern groups are arranged in one-to-one correspondence with and connected with the side patterns (20) of the corresponding group of side pattern groups.
