Abstract
A tire has, in a cross-sectional view in a tire meridian direction when the tire is mounted on a specified rim, inflated to 230 kPa, and in an unloaded state, a radial distance D3 from a point P1 to a point T3 with respect to a radial distance D1 from the point P1 to a point T1 in a range 0.05≤D3/D1≤0.15. The tire has a radial distance D6 from the point P1 to a point T6 with respect to the radial distance D3 from the point P1 to the point T3 in a range 3.00≤D6/D3≤6.00. The tire has a radius of curvature R1 of a first arc passing through the point T3 and points T4 and T5 with respect to a radius of curvature R2 of a second arc passing through the points T1 and T6 and a point T7 in a range 0.40≤R1/R2≤1.00.
