PNEUMATIC TIRE

An object of the present invention is to provide a pneumatic tire capable of significantly increasing the possibility that the tire can be recycled as a base tire for a retreaded tire without so much sacrificing a product life of the tire prior to retreading. Specifically, the present inventions provides a pneumatic tire 1 having a tread portion 2, plural tread grooves including a first tread groove 5 and a second tread groove 15 formed in the tread portion, and a first bottom-up portion 10 with a top surface 10a as a tread wear indicator, the first bottom-up portion being provided at a groove bottom 5b of the first tread groove 5 such that a distance measured in the tire radial direction from an opening end position 5a of the first tread groove to the top surface 10a is x1, comprising: a second bottom-up portion 20 with a top surface 20a as a retread indicator, the second bottom-up portion being provided at a groove bottom 15b of the second tread groove 15 formed in the central region 3 of the tread portion 2 such that a distance measured in the tire radial direction from an opening end position 15a of the second tread groove to the top surface 20a is x2 shorter than said x1.
