A heavy duty tire comprising: a shoulder rib (A1) (shoulder rib (A5)) which is provided to a tread shoulder unit; a second rib (A2) (second rib (A4)) which is adjacent to the shoulder rib (A1) with a circumferential groove (110) (circumferential groove (116)) interposed therebetween and is provided further toward the tire equator side than the shoulder rib (A1); and an uneven wear absorbing rib (B1) (uneven wear absorbing rib (B2)) provided within the circumferential groove (110) and located further toward the inside in the tire radial direction than the tread surfaces of the shoulder rib (A1) and of the second rib (A2). Circumferential narrow grooves (10, 12) having a smaller width than the circumferential grooves (110, 116) are formed in the second ribs (A2, A4). Each circumferential narrow groove (10, 12) is formed in such a manner that, when the tire is mounted on the vehicle, the circumferential groove (10, 12) is located on the outer side of the tire with reference to the center of the second rib (A2, A4) in the tread width direction. |
