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 pneumatic tire includes a land portion provided in a tread portion and including a recess recessed inward in a tire radial direction. The recess includes three or more sides defining an opening that opens to a ground contact surface of the land portion and forming a polygon, and three or more side surface portions defined by the sides and line segments connecting respective vertexes of the sides and a bottom point provided on an inner side of the ground contact surface in the tire radial direction. The side surface portions are formed so as to approach the bottom point as the side surface portions extend inward in the tire radial direction from the ground contact surface.

A pneumatic tire includes center lug grooves disposed at intervals in a tire circumferential direction that extend crossing a tire equator line and include a first groove turning portion and a second groove turning portion; shoulder lug grooves disposed in the intervals between the center lug grooves in the tire circumferential direction extending outward in the tire width direction, an inner end in the tire width direction being disposed outward of an end of the center lug groove in the tire width direction; a pair of circumferential main grooves to which the ends of the center lug grooves and the inner ends of the shoulder lug grooves in the tire width direction alternately connect; and a circumferential secondary groove disposed around the entire circumference of the pneumatic tire that intersects the center lug grooves between the first groove turning portion and the second groove turning portion.

A tread portion is provided with a first block and a second block, which protrudes outward in a tire width direction more than the first block, alternately in a tire circumferential direction in a shoulder region. A first projection is provided in an outer side of the first block, and a second projection is provided in an outer side of the second block. An outside end of the second projection is connected to a side surface of the second block and is arranged closer to an outer side in the tire diametrical direction than an outside end of the first projection. An angle θ1 formed by a side surface of the first projection and a surface of the side wall portion is equal to or smaller than an angle θ2 formed by a side surface of the second projection and the surface of the side wall portion.

The tire includes a lateral groove formed in a tread section and extending in a tire width direction. One groove wall forming the lateral groove includes an inclined surface with curved shape. The inclined surface has an inclination angle, the inclination angle being an angle with respect to a tire radial direction from a groove bottom to a tread surface in a cross section perpendicular to a tire axial direction, that gradually increases from an inner side in the tire width direction on a tire equatorial line side to an outer side in the tire width direction.

It is an object to provide a tire having well-improved fuel efficiency, wet grip performance, abrasion resistance, and wet grip performance at a later stage of abrasion. Provided is a tire comprising a tread part of a rubber composition comprising a rubber component comprising an isoprene-based rubber and a styrene-butadiene rubber, wherein a vinyl content of the styrene-butadiene rubber is greater than 26 mol %, wherein a given ratio A of an ash content of the rubber composition is greater than 25 mol %, wherein the tread part comprises two or more circumferential main grooves extending in a tire circumferential direction, and land parts partitioned by the circumferential main grooves, wherein at least one land part of the land parts comprises at least one given flask-like circumferential groove extending in the tire circumferential direction.

A pneumatic tire is provided. A tread portion includes shallow grooves formed in a road contact surface of each of shoulder blocks, intermediate blocks, and center blocks, defined by a plurality of longitudinal grooves extending in a tire circumferential direction and a plurality of lateral grooves extending in a tire lateral direction, the shallow groove having a smaller groove depth than the longitudinal groove and the lateral groove. The shallow groove extends along the tire lateral direction, and at least one end thereof communicates with the longitudinal groove or the lateral groove. A contour line of the shallow groove is provided with at least one bend point. A sipe is provided in a flat bottom surface of the shallow groove extending along the shallow groove. Among the shallow grooves, center shallow grooves formed in the center block are each provided with a terminating end portion terminating in the center block.

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 pair of circumferential main grooves, a plurality of center lug grooves, and center blocks. The pair of circumferential main grooves are disposed on both sides of a tire equatorial plane in a tire lateral direction. The tire equatorial plane is interposed between the pair of circumferential main grooves. The pair of circumferential main grooves extend in a tire circumferential direction and oscillate in the tire lateral direction. The plurality of center lug grooves have both ends connected to the pair of circumferential main grooves. The center blocks are defined by the center lug grooves and the pair of circumferential main grooves. The center lug grooves have bent portions at two or more positions. The center blocks include center narrow grooves having both ends connected to the pair of circumferential main grooves. The center narrow groove has bent portions at two or more positions.

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.
