Abstract: A tire having a tread portion. The tread portion includes a first shoulder land portion that is defined between a first shoulder main groove and a first tread end. The first shoulder land portion includes: a shoulder lateral groove that extends from the first tread end and ends in the first shoulder land portion; a first sipe that extends from an end of the shoulder lateral groove to the first shoulder main groove; and a second sipe that extends from the first tread end toward the first shoulder main groove, and ends in the first shoulder land portion. A length of the shoulder lateral groove in a tire axial direction is 0.10 to 0.30 times a width of the first shoulder land portion in the tire axial direction.

Abstract: A tire includes a tread portion including at least one land portion having axially spaced first and second ends. The at least one land portion is provided with lateral grooves extending from the first end to terminal ends terminating within the at least one land portion, first sipes each extending along a tire circumferential direction to connect a pair of lateral grooves arranged adjacently in the tire circumferential direction, second sipes extending from the first end toward the first sipes, and third sipes extending from the second end toward the first sipes. The second sipes and the third sipes are arranged without intersecting the lateral grooves.

Abstract: In an apex 34 of a tire 2, a reinforcing portion 48 is located inward of a main body 46 in an axial direction. When a position on an outer surface of the tire 2 at which position a height from a BBL is 14 mm is defined as a first point P1 and a position on the outer surface of the tire 2 at which position a height from the BBL is 20 mm is defined as a second point P2, the reinforcing portion 48 overlaps the first point P1 and the second point P2 in a radial direction. A loss tangent of the reinforcing portion 48 is equal to a loss tangent of the main body 46 or less than the loss tangent. A hardness of the reinforcing portion 48 is equal to a hardness of the main body 46 or greater than the hardness.

Abstract: Provided is a pneumatic tire that can reduce electrical resistance. The pneumatic tire has a tread portion (2), a sidewall portion (3), and a bead portion (4). The pneumatic tire is provided with a toroidal carcass (6) extending between a pair of bead cores (5). The carcass (6) includes a carcass ply (6A) in which juxtaposed carcass cords are covered by topping rubber. An conductive yarn (10) extending between the pair of bead cores (5) is provided along the topping rubber of the carcass ply (6A).
