The present technology provides a pneumatic tire. In a tire meridian cross-sectional view, a profile line (PL1) of a center land portion (X) defined by two center main grooves (14a, 14b) protrudes outward in a tire radial direction further than a standard profile line (PL0). Profile lines (PL2, PL3) of sub-center land portions (Y1, Y2) and shoulder land portions (Z1, Z2) defined outward of the two center main grooves (14a, 14b) in the tire width direction protrude outward in the tire radial direction further than the standard profile line (PL0), the shoulder land portions (Z1, Z2) being defined further outward than the sub-center land portions (Y1, Y2). A pitch count (Po) of a vehicle mounting outer side region and a pitch count (Pi) of a vehicle mounting inner side region satisfy the relationship Po
