PNEUMATIC TIRE

In this pneumatic tire (1), an outer second land portion (32), a center land portion (33), and an inner second land portion (34) have a road contact surface that partially bulges toward the outer side in a tire radial direction from a reference contour line of a tread profile in the cross-sectional view in the tire meridian direction. Additionally, a groove width (Wg1) of an outer shoulder main groove (21), a groove width (Wg3) of an inner center main groove (23), and a groove width (Wg4) of an inner shoulder main groove (24) have a relationship of Wg3 < Wg1 < Wg4, 1.05 ≤ Wg1/Wg3 ≤ 1.25, and 1.10 ≤ Wg4/Wg3 ≤ 1.30.
