A pneumatic tire has a belt cross-sectional width BW as a total width in a tire width direction of a belt layer and a distance Wl as a distance in the tire width direction from an edge on the tread portion side of a run flat liner to an edge of the belt layer. The belt cross-sectional width BW and the distance Wl are such that 0.25≰Wl/(BW/2)≰0.45 is satisfied. A thickness Wr in each of the side wall portions of the pneumatic tire is a thickness in the tire width direction of the run flat liner at a maximum width position, a thickness Ws is a thickness in the tire width direction of a rubber layer at the maximum width position, and the thickness Wr and the thickness Ws are such that 1.2≰Wr/Ws≰1.9 is satisfied.
