To provide a heavy-load tire 2 capable of improving partial wear resistance.SOLUTION: A tire 2 has a nominal flat ratio of 65% or less. The tire 2 is equipped with a tread 4, and a band 34. The band 34 is equipped with a full band 42 that has both ends facing each other across an equatorial plane, and a pair of edge bands 44 located on the outside of the ends of the full band 42 in a diametrical direction. A thin groove 56 is cut on a shoulder land part 54s of the tread 4. The thin groove 56 is equipped with an inner groove wall 62u located on the equatorial plane side to connect a groove port and a groove bottom of the thin groove 56, and an outer groove wall 62s that is located on the outer side of the inner groove wall 62u in the axial direction to connect the groove port and the groove bottom of the thin groove 56. The inner groove wall 62u includes an inner recessed portion 64 depressed inward in an axial direction, on the groove bottom side. The outer groove wall 62s includes an outer recessed portion 66 depressed outward in the axial direction, on the groove bottom side.SELECTED DRAWING: Figure 4 【課題】耐偏摩耗性の向上を達成できる、重荷重用タイヤ２の提供。【解決手段】このタイヤ２は、６５％以下の偏平比の呼びを有する。このタイヤ２は、トレッド４と、バンド３４とを備える。バンド３４は、赤道面を挟んで相対する両端を有するフルバンド４２と、径方向においてフルバンド４２の端の外側に位置する一対のエッジバンド４４とを備える。トレッド４のショルダー陸部５４ｓに細溝５６が刻まれる。細溝５６は、赤道面側に位置し細溝５６の溝口と溝底とを繋ぐ内側溝壁６２ｕと、軸方向において内側溝壁６２ｕの外側に位置し細溝５６の溝口と溝底とを繋ぐ外側溝壁６２ｓとを備える。内側溝壁６２ｕは、溝底側に、軸方向内向きに窪む内側凹部６４を含む。外側溝壁６２ｓは、溝底側に、軸方向外向きに窪む外側凹部６６を含む。【選択図】図４
