In a pneumatic tire having a point-symmetric structure block pattern, narrow and wide outer blocks having different outer end positions in the lateral direction are alternately arranged in the circumferential direction. Among side blocks provided in a side region, large and small blocks are disposed respectively on the outer sides of the narrow and wide outer blocks in the lateral direction. The lateral and side grooves are continuous such that the groove width of the side groove connected to the wide portion of the lateral groove where the outer block converges toward the inner side in the radial direction, and the groove width of the side portion connected to the narrow portion of the lateral groove where the outer block widens toward the inner side in the radial direction, and the side block is tapered with an inner portion block width in the radial direction converges toward the wide portion.

A two-wheeled vehicle tyre includes a tread portion which is provided with a row of crown blocks arranged on a tyre equator and a row of middle blocks arranged axially outwardly of the row of crown blocks. Circumferential pitch lengths of directly adjacent crown blocks are greater than circumferential pitch lengths of directly adjacent middle blocks.

A pneumatic tire of the present disclosure includes a tread, wherein the tread includes: a shoulder main groove; a plurality of shoulder slits; and a plurality of shoulder blocks defined by the shoulder main groove and the shoulder slits, the shoulder blocks include inclined portions inclined inward in the tire radial direction from the shoulder blocks toward an outside in the tire axial direction, the inclined portions include: first inclined portions; and second inclined portions having dents dented more inward in the tire axial direction than the first inclined portions, and the first inclined portions are adjacent to each other with one of the shoulder slits interposed between the first inclined portions and the second inclined portions are adjacent to each other with other shoulder slit interposed between the second inclined portions, the one shoulder slit and the other shoulder slit being paired and defining the shoulder blocks.

A pneumatic tire includes a sidewall extending in a tire radial direction, the sidewall comprises a first side block which protrudes outwardly in a tire axial direction, the first side block comprises a first region which is arranged at an inwardmost location in the tire radial direction of the first side block, a second region which is contiguous with a location toward an exterior in the tire radial direction of the first region, and a third region which is contiguous with a location toward an exterior in the tire radial direction of the second region, the second region protrudes more than the first region, and the third region protrudes more than the second region.

A tire includes a tread having a shoulder region, a shoulder transverse groove being fixedly set in the shoulder region, and a shoulder block row configured by aligning the shoulder blocks in a tire-circumferential direction, in which the shoulder transverse groove has an angle formed by a groove wall and a vertical line drawn from a groove opening end position to a tread surface of the shoulder block within a range of 10 to 20 degrees, and the groove wall and groove bottom are connected by a concave surface with a radius of curvature of at least 6 mm and no more than 15 mm.

A tire includes a tread formed with: circumferential grooves extending continuously in a tire circumferential direction; lateral grooves connecting the circumferential grooves in a tire axial direction; and blocks divided by the circumferential grooves and the lateral grooves. In the lateral groove, a groove bottom is raised to form a tie bar connecting the blocks in the tire circumferential direction. The tie bar is formed with a groove portion penetrating the tie bar in the tire axial direction. In a state where the tire is assembled to a regular rim, filled with a regular internal pressure, loaded with a regular load, and contacting a flat surface at a camber angle 0°, a side wall formed on the tie bar by the groove portion on one side in the tire circumferential direction does not contact a side wall on the other side in the tire circumferential direction.

In a pneumatic tire, a groove depth H1 of each of first and second inclined lug grooves over an entire region from an opening portion to a corresponding one of first or second circumferential main grooves to a terminating end portion within a center land portion has a relationship with a maximum groove depth Hg of the corresponding one of the first or second circumferential main grooves represented by 0.80≤H1/Hg≤1.00. Additionally, a maximum groove depth H2 of each of first and second lateral grooves has a relationship with a groove depth H1e at a terminating end portion of the corresponding one of the first and second inclined lug grooves represented by 0.70≤H2/H1e≤0.90.

A tire includes a tread portion including a circumferential groove and a land portion defined by the circumferential groove, the land portion including a land sidewall facing the circumferential groove. The land sidewall includes a first surface, a second surface located on a groove centerline side of the circumferential groove with respect to the first surface, and a stair portion formed between the first surface and the second surface. The stair portion varies its radial height stepwise in two or more steps in a longitudinal direction of the circumferential groove.

The tire can achieve both cut resistance and mud drainage performance of the sidewall. The tire includes: a tread; sidewalls; and a plurality of side block groups on at least one of the sidewalls. Each of the side block groups protrudes from the sidewall reference plane. Each of the side block groups includes: a first side block; and a second side block. In each of said plurality of side block groups, the fi3 . . . 3rst side block 2 has a groove 23 extending from the second side block 3 toward an inside of the first side block in the tire circumferential direction D3, In each of said plurality of side block groups, the second side block 3 has a slope 35c whose height from the reference plane S2 becomes lower toward the first side block, such that the slope extends into the groove of the first side block.

A pneumatic tire of the present disclosure includes: a pair of main grooves, lateral grooves and longitudinal grooves, wherein a center land, repeats, in the tire circumferential direction, four center blocks, each of the four center blocks includes a recessed portion that is open to the main groove, the lateral groove or the longitudinal groove and has one end closed, when the recessed portions provided in the four center blocks are defined as first to fourth recessed portions, the first recessed portion and the second recessed portion extend in a direction inclined to one direction with respect to the tire equator line, and the third recessed portion and the fourth recessed portion extend in a direction inclined to another direction with respect to the tire equator line, and a groove width of each of the first to fourth recessed portions is 5.0 mm or more.
