摘要: A heavy duty tire 2 includes a tread 4 having a plurality of circumferential grooves 24. The plurality of circumferential grooves 24 divide the tread 4 into a plurality of land portions 26. The plurality of land portions 26 include a plurality of main land portions 32. Each main land portion 32 has a plurality of main lateral grooves 38. The plurality of main lateral grooves 38 divide the main land portion 32 into a plurality of main blocks 40. Each main lateral groove 38 includes a lateral groove body 54 and a bottom sipe portion 56. Each main block 40 has a transverse sipe 70. The transverse sipe 70 includes a sipe body 72 and a tubular portion 74. A circumferential groove 24 located between the adjacent main land portions 38 is a circumferential narrow groove 28 including a body portion 78 and an enlarged width portion 80.

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.
