Abstract: A pneumatic tire includes circumferential grooves aligned in a lateral direction and extending in a circumferential direction, lateral grooves aligned in the circumferential direction and extending to cross the circumferential direction, communicating at ends with the circumferential grooves and defining a block-shaped land portion between the circumferential grooves, two narrow grooves aligned in the lateral direction and extending in the circumferential direction, communicating at ends with a lateral groove and dividing the land portion defined by each of the circumferential grooves and each of the lateral grooves into small land portions, the narrow grooves having a smaller groove width than the circumferential grooves and being formed with a bent portion in an intermediate portion, the bent portion being disposed inward in the lateral direction, and bend points of the bent portions being disposed at positions offset from one another in the circumferential direction.

Abstract: A pneumatic tire includes: a protrusion portion projecting outward in a tire lateral direction disposed in a buttress portion; and a linear portion with a linear shape when viewed in a tire meridian cross section, the linear portion constituting a surface of the protrusion portion at a position inward in a tire radial direction from a corner portion, the corner portion being an end portion of the protrusion portion outward in the tire lateral direction; the corner portion being located within a retreading development width position, which is a range in the tire radial direction in which a boundary for removing a tread when retreading is located; and the linear portion having an angle ranging from 45° to 90° with respect to a horizontal line parallel with a tire rotation axis at a position inward of the linear portion in the tire lateral direction.
