On a cross section in the width direction of a tread in a state with regular internal pressure and under no load, in the overlapping areas, the outermost point in the tread width direction is point (B), and a line passing through the outermost point (C') of a carcass layer in the tread width direction and extending along the tread width direction is line (CC); and on the tire surface, a point through which line (CC) passes is point (C), a line segment extending along the tread width direction from the equatorial center line to point (B) is line segment (BW), a line segment extending along the tread width direction from the equatorial center line to point (C) is line segment (CW), and a line segment connecting point (B) and point (C) is line segment (BC). The ratio (BW/CW) between the length of line segment (BW) and the length of line segment (CW) is in the range of 0.6 to 0.8. The angle (?) formed by line segment (BC) and line segment (CW) is in the range of 50° to 70°. |
