Zusammenfassung:	To suppress or prevent blocking of a sub-groove while making a contact pressure in a tire width direction uniform, in a land part formed with a sub-groove.SOLUTION: A land part 6 is partitioned in a tire width direction into a first part 21 and a second part 20 along a tire profile reference line, by a sub-groove 10. A first maximum projection part 21a having a maximum projection part to the tire profile reference line in the first part 21 is positioned on a side closer to the sub-groove 10 side than a center 21b in the tire width direction of the first part 21. A second maximum projection part 20a having a maximum projection part to the tire profile reference line in the second part 20 is positioned on a side closer to the sub-groove 10 side than the center 21b in the tire width direction of the second part 20.SELECTED DRAWING: Figure 3 【課題】副溝が形成された陸部に関し、タイヤ幅方向の接地圧の均一化を図りつつ、副溝の閉鎖を抑制ないし防止する。【解決手段】陸部６は、副溝１０によって、タイヤプロファイル基準線に沿って第１部分２１と第２部分２０とに、タイヤ幅方向に区画される。第１部分２１においてタイヤプロファイル基準線に対する最大突出量を有する第１最大突出部２１ａは、第１部分２１のタイヤ幅方向の中心２１ｂよりも副溝側１０に位置する。第２部分２０においてタイヤプロファイル基準線に対する最大突出量を有する第２最大突出部２０ａは、第２部分２０のタイヤ幅方向の中心２１ｂよりも副溝１０側に位置する。【選択図】図３
