A pneumatic tire with steering stability performance and uneven wear resistance performance enhanced in a well-balanced manner. A profile line (PL1) of a center land portion (X) defined by the center main grooves protrudes outward in a tire radial direction further than a standard profile line, the standard profile line (PL0) being a curved line including all both end points (A1), (A2), (A3), (A4) of center main grooves (14a), (14b) in a tire width direction. Profile lines (PL2), (PL3) of sub-center land portions (Y1), (Y2) and shoulder land portions (Z1), (Z2) defined outward of the center main grooves in the tire width direction protrude outward in the tire radial direction further than the standard profile line, the shoulder land portions (Z1), (Z2) being defined even further outward than the sub-center land portions (Y1), (Y2). |
