To provide a pneumatic tire achieving improved wear resistance and improved handling performance while maintaining rollover resistance, a tread surface 11 is formed of a center arc 31, a shoulder-side arc 32, and a shoulder arc 33. The tread surface 11 is formed such that a value given by F1=L1/(TDW×0.5) falls in the range of 0.64≦̸F1≦̸0.7, a value given by F2=TR1/OD falls in the range of 1.2≦̸F2≦̸2.0, a value given by F3=TR2/TR1 falls in the range of 0.1≦̸F3≦̸0.2, and a value given by F4=(&bgr;×TDW)/(100×SW) falls in the range of 0.35≦̸F4≦̸0.48, where L1 is an outline range being a width from an equatorial plane 5 to an edge of the center arc 31, TDW is an extended tread width, TR1 is a curvature radius of the center arc 31, TR2 is a curvature radius of the shoulder-side arc 32, OD is a tire outside diameter, SW is a total width, and &bgr; is an aspect ratio.
