Abstract: 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<Pi.

Abstract: A pneumatic tire where 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).

Abstract: Provided is a pneumatic tire including center main grooves, shoulder main grooves, a center land portion, middle land portions, shoulder land portions, and lug grooves provided in each shoulder land portion. The pitch of the lug grooves is changed on the tire circumference. The profile line L1 that defines the road contact surface of the center land portion protrudes further to the outer side in the tire radial direction than the standard profile line L0. The profile line L2 that defines the road contact surface of the middle land portion and the shoulder land portion protrudes further to the outer side in the tire radial direction than the standard profile line L0. The ratio of the groove volume of the lug grooves to the size of the pitch of the lug grooves in the shoulder land portion decreases as the pitch increases, and increases as the pitch decreases.

Further, the profile lines (PL2, PL3) of the sub-center land portions (Y1, Y2) and the shoulder land portions (Z1, Z2) each include an outermost point (A2, A4) of the corresponding center main groove (14a, 14b) in the tire width direction and both end points (A5, A6, A7, A8) of the corresponding shoulder main groove (14c, 14d) in the tire width direction.
