A first belt cord 26a made of organic fibers of a spirally wound belt layer 20 extends at an angle of equal to or less than 5° relative to a tire equatorial plane CL, a second belt cord 36a made of organic fibers of a zigzag belt layer 30 extends at an inclination of an angle of 2° to 45° relative to the tire equatorial plane CL, to folding back points 36b where the second belt cord 36a is folded back at each width directional end edge 30a of the zigzag belt layer 30, and a relation of N95 > N50 is satisfied, where N50 is the number of stacked belt layers of the spirally wound belt layers 20, at a distance of 50% of half the length of a maximum belt width Wb of belt layers 10 from the tire equatorial plane CL, and N95 is the number of stacked belt layers of the spirally wound belt layers 20, at a distance of 95% of half the length of the maximum belt width Wb from the tire equatorial plane CL. With this configuration, a tire capable of realizing both a reduction in weight and enhancement of durability by enhancement of fatigue resistance strength of the belt is obtained.
