摘要： A shoulder land portion includes a main body land portion formed between a thin groove extending in a tire circumferential direction on a tire width direction inner side of a ground contact end and a shoulder main groove, and the main body land portion includes a contact region adjacent to the shoulder main groove provided along the tire circumferential direction and a non-contact region provided along the tire circumferential direction between the thin groove and the contact region. The contact region contacts a road surface in a normal load state, and the non-contact region is recessed to a tire radial direction inner side from a tread surface. The non-contact region does not contact the road surface in the normal road state, and when a length of the non-contact region is W1 and a length of the main body land portion both along the tire width direction is Rw, 0.2Rw≤W1≤0.5Rw.

摘要： A pneumatic tire includes: paired bead portions respectively including annular bead cores and bead fillers disposed on an outer side in a tire radial direction of the bead cores; sidewall portions respectively extending outward in the tire radial direction from the bead portions; a tread portion connected to outer ends in the tire radial direction of the sidewall portions to form a tread; a carcass layer suspended between the bead portions; and a belt layer provided on an outer side in the tire radial direction of the carcass layer in the tread portion. The carcass layer has a first ply that continuously extends between the bead portions and that has opposite end portions and a second ply that extends from a position in contact with an inner peripheral face of an end portion, wherein the second ply has higher tensile strength than the tensile strength of the first ply.

摘要： A non-pneumatic tire includes a support structure for supporting a load from a vehicle. The support structure includes an inner annular portion, an outer annular portion concentrically provided on an outer side of the inner annular portion, and a plurality of connecting portions which connect the inner annular portion and the outer annular portion to each other and are provided in a tire circumferential direction independently of one another, the plurality of connecting portions are configured such that elongated plate-like first connecting portions and elongated plate-like second connecting portions are arrayed along the tire circumferential direction, an angle α and an angle β, the angles being formed by an inner circumferential surface of the outer annular portion and both side surfaces of each of the connecting portions, both surfaces facing the tire circumferential direction, are 75° or more and 120° or less.

摘要： A pneumatic tire is provided with tread rubber that forms a contact patch; and a belt layer which is disposed toward the interior in a tire radial direction from the tread rubber. A shoulder lug portion is provided with a narrow groove that partitions the shoulder lug portion into a main body portion and into a sacrificial portion. A plurality of concavities are open toward both the contact patch at the main body portion and the groove side face, wherein innermost ends in the tire width direction of the respective concavities are disposed so as to be at the same location in the tire width direction as an outermost end in the tire width direction of the belt layer or are arranged toward the exterior in the tire width direction from the outermost end in the tire width direction of the belt layer.

摘要： A tire has cap rubber that forms a contact patch. The cap rubber has a plurality of lugs. A shoulder lug, which among the plurality of lugs is that which is located outwardmost in a tire width direction, has a narrow groove that extends in the tire circumferential direction and that partitions the shoulder lug into a main lug portion toward the interior in the tire width direction, and a sacrificial lug portion toward the exterior in the tire width direction; and low-modulus rubber, for which stress at a given elongation is lower than that of the cap rubber, is arranged at a corner where the contact patch at the main lug portion and a groove side face toward the interior in the tire width direction which forms the narrow groove intersect.

摘要： A pneumatic tire includes a tread portion that is provided with two block rows formed of three circumferential grooves and a plurality of first transverse grooves. A block that configures the block rows has a hexagonal shape, and has a diagonal extension line passing through a pair of vertices positioned in the central portion in the tire-circumferential direction, the diagonal extension line overlapping, in the tire-circumferential direction, the first transverse groove of the adjacent block rows. The block has a first sipe that is terminated within a block extending in the tire-width direction. The first sipe is provided at a position shifted from the diagonal extension line in the tire-circumferential direction and in a region interposed between planes that are formed by extending, in a direction in which the first transverse groove extends, from a pair of groove wall surfaces of the first transverse groove of the adjacent block rows.
