To reduce damage to a projecting part of a side wall part.

This pneumatic tire 1 is mounted on a wheel 10 in which a height H of a rim flange part 11 on one side with a rim diameter R made as a reference is larger than that of a rim flange part on the other side, is located at the tire radial direction outside of an outer peripheral side end part of the rim flange part 11 in a rim assembly state of the tire 1, and has the projecting part 61 projecting in a tire width direction in the side wall part. When a point P on a profile line at a position of 30[%] of a tire cross section height SH from the tire radial direction outside is taken in cross-sectional view of a tire meridian direction, the profile line of the side wall part from the point P to a top point of the projecting part 61 is constituted of a substantially circular arc having a center at the tire width direction inside.
