Provided is a tire in which a tread half portion has a circumferential groove and land portions, an outline of a tread surface of the tread half portion includes circular arcs, the circular arc having a minimum radius of curvature is present within the outline of the land portion adjacent to a tread edge, the tread half portion has a base rubber layer, and a cap rubber layer, the base rubber layer has a lower storage modulus than the cap rubber layer, and an end of the layer in a tire width direction on a tread edge side is located in a region extending as much as 0.06 times a ground contact width of the tread half portion on each of both tire widthwise sides of a center of a tire widthwise length of an outline portion occupied by the circular arc having the minimum radius of curvature.

A tire including a tread wear indicator is provided. The tire includes a pair of sidewalls, in which each sidewall extends from a respective bead area to a tread. The tread includes a plurality of main circumferential grooves, in which the main circumferential grooves are disposed in and proximate an axial center area of the tread. At least one shallow groove is formed in the tread, and each shallow groove includes a depth relative to the surface of the tread that is less than a depth of each of the main circumferential grooves. A primary tread wear indicator is disposed in at least one of the main circumferential grooves, and a secondary tread wear indicator is disposed in the shallow groove.

A tread for a tire includes: a first tread zone extending circumferentially, continuously, and entirely around the tire, the first tread zone being formed of a first compound; a second tread zone extending circumferentially, continuously, and entirely around the tire, the second tread zone being formed of a second compound different from the first compound; and a boundary groove axially separating the first tread zone from the second tread zone, the first tread zone, the second tread zone, and the boundary groove entirely forming the tread, the boundary groove having an axial centerline disposed an axial distance from an equatorial plane of the tire. The first tread zone has a first circumferential groove and a sidewall portion defining an intermediate circumferential rib of the first tread zone and a shoulder circumferential rib of the first tread zone.

A pneumatic tire includes at least four circumferential main grooves that extend in a tire circumferential direction; and at least five land portions defined by the circumferential main grooves. The center land portion and the left and right second land portions each include through lug grooves that are inclined at a predetermined inclination angle with respect to the tire lateral direction and extend through the land portion in the tire lateral direction.
