The first profile P1 includes a first arc 11, a second arc 12, and a third arc 13. A radius TR2 of curvature of the second arc 12 is 30% to 40% of a radius TR1 of curvature of the first arc 11. A radius TR3 of curvature of the third arc 13 is 25% to 40% of the radius TR2 of curvature of the second arc 12. A second connection point 15 at which the second arc 12 and the third arc 13 are connected to each other is disposed inward of the first tread end T1 in the tire axial direction. A distance La by which the second connection point 15 and the tire equator C are distant in the tire axial direction is 30% to 34% of a cross-sectional width of the tire. The third arc 13 extends outward in the tire axial direction beyond the first tread end T1.",
