  "textContent": "A tyre comprises a tread portion. The tread portion includes a shoulder main groove extending continuously in a zigzag manner in a tyre circumferential direction on a side of a tread edge, a plurality of middle lateral grooves each extending inwardly in a tyre axial direction from the shoulder main groove, and a plurality of middle blocks divided by the plurality of the middle lateral grooves. Each of the middle blocks has a ground contacting surface defined between a first edge and a second edge extending in the tyre circumferential direction. At least one of the middle blocks has a full sipe extending so as to connect between the first edge and the second edge and having at least one bent portion, and a semi-sipe extending linearly from the first edge or the second edge and terminating within the at least one of the middle blocks.",
