摘要： An object is to, in an aircraft tire, promote heat dissipation from circumferential direction grooves of a tread and improve durability of the tire. Plural circumferential direction grooves (central side circumferential direction grooves (14), edge portion side circumferential direction grooves (16)) that extend in a tire circumferential direction are formed in a tread (12). In a tire circumferential direction cross-section, a groove bottom (18) of at least one of the circumferential direction grooves has a wave shape having amplitude in a tire radial direction.
