An object is to make it make it possible to, before a protecting layer is exposed, visually recognize that a final stage of wear of a tread has been reached.;A pneumatic tire (10) for an aircraft has: a carcass ply (12) that spans between a pair of bead portions; a belt layer (14) that is provided at a tire radial direction outer side of a crown portion (12A) of the carcass ply (12); a protecting layer (16) that is provided at a tire radial direction outer side of the belt layer (14); a tread (18) that is provided at a tire radial direction outer side of the protecting layer (16), and at which ribs (30, 32, 34) are demarcated and formed by circumferential direction grooves; and filaments (20) that are provided between the protecting layer (16) and the tread (18), or within the tread (18), that extend in a tire axial direction, and that are disposed with an interval therebetween in a tire circumferential direction. |
