PROBLEM TO BE SOLVED: To increase durability of a tire by accelerating radiation of heat from a circumferential groove of a tread of the aircraft tire.SOLUTION: A plurality of circumferential grooves (a central-side circumferential groove 14 and an end-side circumferential groove 16) elongated in a circumferential direction of a tire are formed on a tread 12. In a cross-section in the circumferential direction of the tire, a groove bottom 18 of the at least one circumferential groove has a wave shape having an amplitude in the radial direction of the tire. |
