    摘要: A heavy duty tire 2 includes a tread 4 having a tread surface 6. A circumferential groove 10 located between middle land portions 12m on a first end side and a second end side of the tread surface 6 is a circumferential narrow groove 36. The circumferential narrow groove 36 includes a tapered portion 40 including a groove opening 14, and a body portion 42 including a groove bottom 34. When the tire 2 comes into contact with a road surface, a pair of groove walls 30 come into contact with each other at the body portion 42. The tapered portion 40 includes wide portions 44 in which the groove opening 14 is wide, and narrow portions 46 in which the groove opening 14 is narrow. The wide portions 44 and the narrow portions 46 are arranged alternately in a circumferential direction.
