A first belt cord made of organic fibers of a spirally wound belt layer extends at an angle of equal to or less than 5° relative to a tire equatorial plane, a second belt cord made of organic fibers of a zigzag belt layer extends at an inclination of an angle of 2° to 45° relative to the tire equatorial plane, to folding back points where the second belt cord is folded back at each width directional end edge of the zigzag belt layer, and a relation of N>Nis satisfied. Nis the number of stacked belt layers of the spirally wound belt layers, at 50% of half the length of a maximum belt width of belt layers from the tire equatorial plane. Nis the number of stacked belt layers of the spirally wound belt layers, at 95% of half the length of the maximum belt.
