The first shoulder lateral grooves 10 include first groove portions 11 that extend in the tire axial direction from the tread edges Te, second groove portions 12 that extend farther inward in the tire axial direction than the first groove portions 11 and moreover extend at different positions in the tire circumferential direction than the first groove portions 11, and third groove portions 13 connecting the first groove portions 11 and the second groove portions 12.

A tire includes, in a tread portion, a pair of shoulder main grooves, a crown region between the shoulder main grooves, and shoulder regions disposed outside of the shoulder main grooves in a tire axial direction. Land ratios of the crown region and the shoulder regions are respectively 40%-60%. In the crown region, a plurality of middle blocks are arranged on both sides of a tire equator, and each middle block has a longitudinal shape in which a length in the tire circumferential direction is larger than a length in the tire axial direction.

A tyre comprises a tread portion having a land region including a ground contacting surface defined between a first vertical edge and a second vertical edge and a lateral groove including a first portion extending from the first vertical edge, a second portion extending from the second vertical edge, and a connection portion connecting therebetween. The connection portion is a portion between a first small edge protruding circumferentially from the first portion and a second small edge protruding toward a circumferentially opposite side to the first small edge. A length in the tyre circumferential direction of each of the first and second small edges is smaller than a maximum groove width of each of the first and second portions. At least a part of the connection portion has a raised bottom portion having a depth smaller than that of the lateral groove at the first and second vertical edges.

A tyre includes a tread portion provided with an outer main groove, an inner main groove, and a middle main groove. Each of the main grooves has a pair of groove edges arranged on both sides in a tyre axial direction and extending in a tyre circumferential direction. At least one of the groove edges includes circumferential portions extending in the tyre circumferential direction and axial portions inclined at larger angles than the circumferential portions with respect to the tyre circumferential direction. When an axial portion total length is a sum of axial lengths of the axial portions included in the main grooves, an axial portion total lengths L1, L2, and L3 of the outer main groove, the middle main groove, and the inner main groove, respectively, satisfy Expressions (1) and (2) shown below;
L1>L3  Ex. (1)
L1≥L2≥L3  Ex. (2).

Center land portions of a tire each include a circumferential narrow groove extending in a tire circumferential direction, and a first lateral groove opening to one edge portion of each of the center land portions at one end and connecting to the circumferential narrow groove at the other end, and a second lateral groove opening to the other edge portion of the center land portion at one end and connecting to the circumferential narrow groove at the other end. Further, the circumferential narrow groove has a zigzag shape formed by repeatedly connecting a first long portion, a first short portion, a second long portion, and a second short portion. Furthermore, the first lateral groove connects to the first long portion of the circumferential narrow groove having the zigzag shape, and the second lateral groove connects to the second long portion of the circumferential narrow groove having the zigzag shape.

A tire includes a tread portion being provided with a first circumferential groove extending continuously in the tire circumferential direction, and a first land portion adjacent to the first circumferential groove. The first land portion includes a ground contact surface, a land sidewall on a first circumferential groove side, and a recess that opens across both the ground contact surface and the land sidewall. The recess has an opening defined by a V-shaped first edge and a V-shaped second edge respectively extending on the ground contact surface and the land sidewall. The recess has a circumferential maximum length L1 of from 6.0 to 9.0 mm. The recess has a maximum depth d1 of from 15% to 40% of a maximum depth of the first circumferential groove. The recess has an axial maximum length L2 of from 3.0 to 5.0 times the depth d1.

A motorcycle tire includes a tread portion including a crown portion that is a region of 50% of a tread development width centered on a tire equator, a first shoulder portion that is an outer region of the crown portion, and first lateral grooves. Each lateral groove includes a first groove portion in the crown portion, a second groove portion in the first shoulder portion, and a third groove portion connecting the first and second groove portions. A groove depth and a groove width of the third groove portion are respectively smaller than groove depths and groove widths of the first groove portion and the second groove portion, respectively. More than 80% of a tire axial length of the third groove portion is in the first shoulder portion.

A tire for running on rough terrain for which an intended tire rotational direction is specified. The tread portion is provided with blocks raised from a tread base portion. Each block has a first side wall surface comprising a radially outer portion extending substantially straight and radially inwardly, while inclining toward the toe side in the intended tire rotational direction, and a radially inner portion extending from the radially outer portion to the tread base portion while curving in an arc shape. The radially outer portion has a radial length of from 30% to 70% of a radial height of the block.

A tire for running on rough terrain for which an intended tire rotational direction is specified, and which comprises a tread portion provided with crown blocks disposed on the tire equator. Each of the crown blocks comprises a V-shaped crown block main portion which bends convexly toward a circumferential direction opposite to the intended tire rotation direction, and only two crown fin portions projecting from the crown block main portion toward the above-said circumferential direction opposite to the intended tire rotation direction.

A tire includes a tread portion. The tread portion has a main groove extending continuously in a tire circumferential direction, and a land portion adjacent to the main groove. The land portion has lateral grooves extending from the main groove in a tire axial direction. Each of the lateral grooves has a first portion communicating with the main groove, and a second portion connected to the first portion. The first portion has a larger groove width than the second portion and has a smaller groove depth than the second portion.
