This pneumatic tire has a side portion and a clinch portion, wherein: in a meridian cross section, the distance Ha from a bead baseline to the outside portion in the width direction of the clinch portion is greater than the distance Hb to the inside portion in the width direction; the complex modulus E*s of the side portion, as measured at 70°C, a frequency of 10 Hz, an initial distortion of 5%, and a distortion rate of 1%, is less than the complex modulus E*c of the clinch portion; and, furthermore, formula (1) and formula (2) below are satisfied, where Wt is the cross-sectional width of the tire when installed to a standardized rim and filled with air to an internal pressure of 250 kPa, Dt is the outer diameter, and the virtual volume V is the volume of the space occupied by the tire. 1600 ≤ Dt 2 × π / 4 / Wt ≦ 2827.4 V + 1.5 × 10 7 / Wt ≦ 2.88 × 10 5",
