PNEUMATIC TIRE

In order to provide both reduction in rolling resistance and ensuring of traction characteristics of a pneumatic tire (1) in a compatible manner, in a land portion (20), a lug groove (40) is disposed extending in the tire width direction and opening to two circumferential main grooves (30) defining the land portion (20), a groove width (LW) of the lug groove (40) is in a range 0.5 mm ≤ LW ≤ 3.0 mm, the lug groove (40) includes a lug groove central portion (51) and lug groove edge portions (53) located on both sides of the lug groove central portion (51) in an extension direction of the lug groove (40), and a groove depth (Dc) of the lug groove central portion (51), a groove depth (De) of the lug groove edge portion (53), and a groove depth (Dg) of the circumferential main groove (30) have a relationship in a range 0.05 ≤ (Dc/Dg) ≤ 0.40 and in a range 0.60 ≤ (De/Dg) ≤ 1.00, and a width (RWc) of the lug groove central portion (51) in the tire width direction and a width (RWa) of the land portion (20) in the tire width direction have a relationship in a range 0.30 ≤ (RWc/RWa) ≤ 0.7.
