Abstract: A tire 2 of the present invention includes a pair of fillers 20 turned up around beads 10. Each filler 20 has multiple cords made of steel and aligned with each other. In the tire 2, an outer surface of a chafer 8 has a bottom surface 26 that contacts with a seat surface of a rim 30. When a reference line M represents a straight line that contacts with the bottom surface 26 in a cross-section obtained by cutting the tire at the plane perpendicular to the circumferential direction, the bottom surface 26 has a depression 66 that is shaped so as to project radially outward of the reference line M. A ratio (D/L) of a maximum depth D of the depression 66 to a width L of the depression 66 is greater than or equal to 0.007 and not greater than 0.060.
