A pneumatic tire is provided, the pneumatic tire including a tread portion, sidewall portions, and bead portions, and the pneumatic tire includes, in the tread portion, a center main groove extending in a tire circumferential direction and a shoulder main groove extending in the tire circumferential direction on the outside of the center main groove; a land portion between the main grooves; lug grooves extending inward in a tire lateral direction from the shoulder main groove and terminating without communicating with the center main groove; a bent portion bending toward one side in the tire circumferential direction, at a terminating end of each of the lug grooves; and a raised bottom portion included in the bent portion, creating a level difference with respect to a lug groove, and being shallower than the lug groove.

A tire includes knob sets having leading edge bevels connected by a ramp. The leading edge bevels may be offset in their positions or angles. Each knob set includes a first knob attached to a second knob. The knobs in each set may differ in lengths or in the angles of the leading edge bevels. Each knob set shares a common base and includes a pair of elongate outermost surfaces divided by an optional axial channel. Each knob set includes a lateral edge, medial edge and a trailing edge. Transverse rows of two or more knob sets may vary in lateral spacing between knob sets to provide narrow and wide rows in an alternating pattern. Knob sets may also be included on sidewalls of the tire.

A run-flat tire includes a belt reinforcing layer outward of a belt layer in a tire radial direction and reinforcing rubber in sidewall portions. Where a center region is a region of a tread portion in which a center land portion corresponding to a land portion included in land portions in a tread portion and located closest to a tire equatorial plane is positioned, the belt reinforcing layer includes a center reinforcing portion in which more pieces of the belt reinforcing layer are layered at a position of the center region than at positions other than the position of the center region, and in the belt reinforcing layer, a width Wc of the center reinforcing portion in a tire lateral direction with respect to a thickness Gr of the side reinforcing rubber at a tire maximum width position is within a range of 0.5 Gr≤Wc≤2.0 Gr.

A tyre for running on rough terrain has a tread portion including a plurality of blocks and tread crossing grooves extending between a first tread edge and a second tread edge without intersecting the blocks. Each of the tread crossing grooves includes a soil discharging space having a width of at least 10 mm or more and extending linearly so as to connect between the first tread edge and the second tread edge. The soil discharging space is inclined at an angle of 30 degrees or more and 50 degrees or less with respect to a tyre axial direction.

Steering stability performance on dry road surfaces and steering stability performance on wet road surfaces are improved. A land portion width Wcc of a center land portion (31) and a land portion width Wco of an outer side middle land portion (32) satisfy a relationship of Wcc<Wco. In addition, a ground contact surface (10) of each of the outer side middle land portion (32) and an outer side shoulder land portion (34) is formed to protrude toward an outer side in a tire radial direction with respect to a reference profile PRco, PRso, and a protruding amount Hco of the outer side middle land portion (32) and a protruding amount Hso of the outer side shoulder land portion (34) satisfy a relationship of Hco<Hso.

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.

Present invention provides a tread for a tire being provided with a plurality of grooves extending in an orientation having a non-zero angle A with circumferential orientation, at least two circumferentially adjacent grooves delimiting a contact element, the contact element having at least one incision extending in an orientation substantially parallel to the grooves, the contact element being delimited into sub-contact elements, on a plane perpendicular to the orientation in which the plurality of grooves being extending and to the contact face, each sub-contact elements having a length Ls between the plurality of grooves and the at least one incision or between two incisions, an outermost portion of each the sub-contact element having a radius Rs smaller than a radius Rt of an outline OL of the tread at an intersection between the outline OL and the outermost portion, the radius Rs of the outermost portion of the sub-contact elements is smaller than or equal to 16.0 mm and greater than or equal to 5.0 mm.

Provided is a pneumatic tire. At least three blocks of a plurality of blocks formed on a tread portion, which include an outermost block positioned on an outermost side in a tire lateral direction and are adjacent to each other in the tire lateral direction, and at least two longitudinal grooves positioned between the at least three blocks are arranged on a platform, which is raised from a groove bottom of a lateral groove, has a flat top surface, and has a shape protruding toward both sides in a tire circumferential direction with respect to the at least three blocks. On a groove bottom of a longitudinal groove adjacent to the outermost block, a raised bottom portion raised from the groove bottom of the longitudinal groove is provided. The raised bottom portion connects the outermost block and the block adjacent to the outermost block.

An off-road tyre includes a tread portion being provided on a tread edge side with shoulder blocks arranged in a tyre circumferential direction. The shoulder blocks include at least one first shoulder block and at least one second shoulder block having a circumferential length greater than that of the at least one first shoulder block. The at least one first shoulder block includes a first ground contact surface, a second ground contact surface protruding outwardly from the first ground contact surface in a block height direction, and a first shallow groove extending between the first ground contact surface and the second ground contact surface.

A motorcycle tyre for off-road includes a tread portion including a bottom surface and connected bodies. The block connected bodies each include blocks protruding from the bottom surface and tie-bars protruding from the bottom surface with a height smaller than that of the blocks to connect the blocks with one another. The block connected bodies include a first connected body whose blocks and tie-bars are arranged so as to surround the bottom surface at least partially. The first connected body includes a first end block located on a first end in a longitudinal direction of the first connected body and a second end block located on a second end in the longitudinal direction of the first connected body. The first end block and the second end block are adjacent with one another, and no tie-bar connecting the first end block and the second end block is provided.
