The tire 2 includes a tread 4, a pair of sidewalls 6, a pair of beads 10, and a carcass 12. Each bead 10 includes a core 30 and an apex 32. A ratio (A/H) of a height A of the apex 32 to a cross-sectional height H is not less than 5% and not greater than 15%. In a meridian cross-section of the tire 2 in a standard state, a contour of a side surface S including a maximum width position PW includes two arcs tangent to each other at the maximum width position PW. Of the two arcs, the arc located inward of the maximum width position PW in a radial direction is a first arc, and the arc located outward of the maximum width position in the radial direction is a second arc. A ratio (R1/R2) of a radius R1 of the first arc to a radius R2 of the second arc is not less than 70% and not greater than 91%.",
