A tire comprising a tread portion having a designated mounting direction to a vehicle, wherein the tread portion includes an outer tread edge (To) located on an outer side of the vehicle when the tire is mounted on the vehicle, an outer shoulder main groove provided between the outer tread edge (To) and a tire equator, an outer shoulder land portion demarcated between the outer tread edge (To) and the outer shoulder main groove, the outer shoulder land portion having a plurality of outer shoulder lateral grooves which extend from the outer tread edge (To) and terminate within the outer shoulder land portion, and an outer middle land portion adjacent to a tire equator side of the outer shoulder main groove, and in a meridian cross-section including a tire rotation axis in a normal state where the tire is mounted on a normal rim and inflated to a normal internal pressure, the tread portion has a profile which is curved convexly outward in a tire radial direction, a tread surface of the outer middle land portion includes a first profile extending from a groove edge of the outer shoulder main groove at least to a center in a tire axial direction of the tread surface of the outer middle land portion and composed of a circular arc having a first radius of curvature, and a tread surface of the outer shoulder land portion includes a second profile composed of a circular arc having a second radius of curvature, and a third profile extending from an inner end in the tire axial direction of the second profile to a groove edge of the outer shoulder main groove and composed of a circular arc having a third radius of curvature smaller than the second radius of curvature, characterized in that an inner end in the tire axial direction of each of the outer shoulder lateral grooves is located inward in the tire axial direction of a point of intersection of the second profile and the third profile. the tread portion includes an outer tread edge (To) located on an outer side of the vehicle when the tire is mounted on the vehicle, an outer shoulder main groove provided between the outer tread edge (To) and a tire equator, an outer shoulder land portion demarcated between the outer tread edge (To) and the outer shoulder main groove, the outer shoulder land portion having a plurality of outer shoulder lateral grooves which extend from the outer tread edge (To) and terminate within the outer shoulder land portion, and an outer middle land portion adjacent to a tire equator side of the outer shoulder main groove, and in a meridian cross-section including a tire rotation axis in a normal state where the tire is mounted on a normal rim and inflated to a normal internal pressure, the tread portion has a profile which is curved convexly outward in a tire radial direction, a tread surface of the outer middle land portion includes a first profile extending from a groove edge of the outer shoulder main groove at least to a center in a tire axial direction of the tread surface of the outer middle land portion and composed of a circular arc having a first radius of curvature, and a tread surface of the outer shoulder land portion includes a second profile composed of a circular arc having a second radius of curvature, and a third profile extending from an inner end in the tire axial direction of the second profile to a groove edge of the outer shoulder main groove and composed of a circular arc having a third radius of curvature smaller than the second radius of curvature, a second profile composed of a circular arc having a second radius of curvature, and a third profile extending from an inner end in the tire axial direction of the second profile to a groove edge of the outer shoulder main groove and composed of a circular arc having a third radius of curvature smaller than the second radius of curvature, characterized in that an inner end in the tire axial direction of each of the outer shoulder lateral grooves is located inward in the tire axial direction of a point of intersection of the second profile and the third profile.
