When a pneumatic tire is in a reference state of being fitted with a rim that is one inch larger than a regular rim in width, of holding 15 kPa internal pressure, and of being under no load, then a tread thickness distribution curve represented by f(y)=1−t(y)/t(0) is 0.01 to 0.03 when y=0.3; 0.03 to 0.06 when y=0.4; and 0.06 to 0.10 when y=0.5, where y denotes a ratio of a distance in an axial direction from an equator surface relative to a distance L in the axial direction between the equator surface and a maximum width position of a carcass, and t(y) denotes a tread thickness corresponding to a distance in a radial direction between an outer surface of the carcass and an outer surface of a tread at an axial direction position corresponding to y.
