PROBLEM TO BE SOLVED: To satisfy both of steering stability in high speed traveling and durability in high speed traveling with a camber.SOLUTION: In a pneumatic tire 1, at least four ribs 23 extended along a tire circumferential direction are formed on a tread surface 21 by at least three main grooves 22 extended along the tire circumferential direction, and inside and outside directions of a vehicle when being attached to the vehicle are designated. At least one rib 23 in a region outside the vehicle from a tire equatorial plane CL is protruded outside in a tire radial direction from a contour line L of the tread surface 21 and at least one rib 23 inside the vehicle from the tire equatorial plane CL is recessed inward in the tire radial direction from the contour line L, and the center of the radius of curvature of the line of the recess is positioned outside in the tire radial direction from the tread surface 21. |
