A tire (10) includes a stiffening structure (50) comprising stiffening elements (52) anchored in the crown (12) and extending into the toroidal cavity (35) between a radially inner anchor point (54A, 54B) and a radially outer anchor point (56A, 56B). The tread (14) has a profile height and comprises a plurality of ribs (102, 104, 106, 108, 110), two adjacent ribs being axially separated from each other by a main circumferential cut-out (112, 114, 116, 118) having a depth greater than or equal to 50% of the profile height. The radially outer anchor point (56A, 56B) is aligned with one of the ribs (102, 104, 106, 108, 110).

A tire structure disposed at a rim is provided. The tire structure includes a tire body, a flexible sealing member and a nozzle. The tire body is ring-shaped and includes a groove and two beads. The flexible sealing member is connected to the tire body to form an inflating space with the groove, and the flexible sealing member includes a through hole. The nozzle is disposed at the flexible sealing member. The nozzle includes a base and a valve stem. The base includes a screw hole and is disposed at a far side of the flexible sealing member. The screw hole corresponds to the through hole. The valve stem includes a fastening end and an inflating channel. The fastening end is configured to insert into the screw hole, and the inflating channel is configured to allow the gas to pass therethrough.

A pneumatic tire includes a tread portion provided with a circumferentially and continuously extending zigzag shoulder main groove located adjacent to a tread edge, a shoulder lateral groove extending axially outwardly from the shoulder main groove and a central lateral groove extending axially inwardly from the shoulder main groove. The shoulder main groove includes an inner corner portion protruding axially inwardly. The central lateral groove includes a first groove portion, a second groove portion and a confluence portion at which the first groove portion and the second groove portion meet. The confluence portion of the central lateral groove is communicated with the inner corner portion of the shoulder main groove. The shoulder lateral groove is located so that an extended portion in which the shoulder lateral groove is extended axially inwardly overlaps with the confluence portion at least partially.
