A heavy duty tire 2 includes a tread 4. The tread 4 has a plurality of circumferential main grooves 12. The plurality of circumferential main grooves 12 include a circumferential narrow groove 38. The circumferential narrow groove 38 includes a body portion 30, a tapered portion 32, and a widened portion 34. When the tread 4 comes into contact with a road surface, a pair of wall surfaces 24 of the circumferential narrow groove 38 come into contact with each other at the body portion 30.
