A pneumatic tire for aircraft comprising:

• a pair of bead portions;
• a carcass comprising one or more carcass plies spanning the pair of bead portions in a toroidal shape;
• and
• a belt consisting of three or more belt layers disposed radially outwardly of the crown portion of the carcass;
• wherein,
• the belt includes,
• one or more spiral belt layers consisting of a ribbon-like first strip member made with a first belt cord coated with rubber, spirally wound in the circumferential direction of the tire, and
• two or more zigzag belt layers consisting of a ribbon-like second strip member made with a second belt cord coated with rubber, spirally wound in the circumferential direction of the tire so that the following manners are repeated:
• extending from one tire width direction end to the other tire width direction end, folded back at the other tire width direction end, extending from the other tire width direction end to the one tire width direction end, folded back at the one tire width direction end, and extending again from the one tire width direction end to the other tire width direction end,
• the zigzag belt layers include one or more inner zigzag belt layers and one or more outer zigzag belt layers located outside the inner zigzag belt layers in the tire radial direction,
• the belt layers are arranged in the following order from the inside of the tire radial direction:
• the inner zigzag belt layers, the spiral belt layers, and the outer zigzag belt layers, and
• among the belt layers, the inner zigzag belt layer has the maximum width in the tire width direction.
