Provided is a pneumatic tire with which it is possible to substantially improve the rate at which usage as a base tire for retreading is possible without significantly retarding the useful lifetime of the tire prior to retreading. This pneumatic tire (1) has a plurality of tread grooves disposed in a tread part (2), and has a first protrusion part (10) at the groove bottom (5b) of a first tread groove (5) thereamong, which is a tread wear indicator which has a peak face (10a) with a distance (x1) from an aperture end location (5a) of the groove when measuring in the tire diameter direction. This pneumatic tire (1) has a second protrusion part (20) in the groove bottom (15b) of a second tread groove (15) which is disposed in the center region (3) of the tread part (2), which is a tread indicator which has a peak face (20a) with a distance (x2) which is shorter than the distance (x1) from an aperture end location (15a) of the groove when measuring in the tire diameter direction.
