摘要： The tire can have a tread portion. The tread portion can include a first shoulder circumferential groove and a first shoulder land portion. In the first shoulder land portion, a plurality of first shoulder lateral grooves can be disposed. At least one of the first shoulder lateral grooves can include an inner end connected to the first shoulder circumferential groove, a maximum groove width portion, and an outer portion. The maximum groove width portion can be at almost the center, in a tire axial direction, of a ground contact surface of the first shoulder land portion. A groove width at the inner end and a groove width, on a first tread end, of the first shoulder lateral groove can each be less than the maximum groove width. A groove width of the outer portion can be reduced outward in the tire axial direction.

摘要： A tyre comprising a tread portion comprising first and second tread edges, a crown groove extending continuously in a tyre circumferential direction in a crown portion of the tyre, a first land portion between the first tread edge and the crown groove, and a second land portion extending from the crown groove towards the second tread edge. The first land portion is provided with first lateral grooves connected to the crown groove and extending from the crown groove in the direction to the first tread edge, and the second land portion is provided with second lateral grooves connected to the crown groove and extending from the crown groove in the direction to the second tread edge. The first land portion is divided into first blocks by the crown groove and the first lateral grooves, and the second land portion is divided into second blocks by the crown groove and the second lateral grooves.
