The rim for a pneumatic tire according to the present invention is provided with a pair of bead seat portions separated from each other in a rim width direction and a flange portion extending outwards in a rim radial direction from a rim width direction outer end of each bead seat portion. A rim radial direction outer end of the flange portion is recurved outwards in the rim width direction. A radius of curvature of a surface of the flange portion at a rim width direction outer end portion of the flange portion is at least 0.4 times and at most 1.0 times a radius of curvature of the surface of the flange portion at a rim width direction central portion of the flange portion.",
