Provided is a pneumatic tire that improves, in a balanced way, maneuvering stability performance, hydroplaning resistance performance, and uneven-abrasion resistance performance. A profile line (PL1) of a center land section (X) projects further outward in the tire radial direction than a standard profile line (PL0). Including the tire width-direction outermost points (A2, A4) of center principal grooves (14a, 14b) and the tire width-direction end points (A5, A6, A7, A8) of shoulder primary grooves (14c, 14d), profile lines (PL2, PL3), of subcenter land sections (Y1, Y2) and shoulder land sections (Z1, Z2) which are partition-formed in sequence further outward in the tire width direction than the two center principal grooves (14a, 14b), project further outward in the tire radial direction than the standard profile line (PL0). The groove area ratio (Go) of a vehicle mount outside region and the groove area ratio (Gi) of a vehicle mount inside region satisfy the relationship Gi > Go. |
