PROBLEM TO BE SOLVED: To provide a pneumatic tire for improving maneuvering stability performance, noise-vibration resistant performance and uneven wear resistant performance in a well-balanced state.SOLUTION: In a tire meridian cross-sectional view, a profile line PL1 of a center land part X partitioned-formed by two center main grooves 14a and 14b, projects to the outside in the tire radial direction more than a reference profile line PL0. Profile lines PL2 and PL3 of sub-center land parts Y1 and Y2 and shoulder land parts Z1 and Z2 partitioned-formed in order on the outside in the tire width direction more than the two center main grooves 14a an 14b, project to the outside in the tire radial direction more than the reference profile line PL0. The pitch number Po of a vehicle-installing outside area and the pitch number Pi of a vehicle-installing inside area, satisfy the relationship of Po<Pi.SELECTED DRAWING: Figure 2 |
