摘要

A run flat tire support body, a method of manufacturing the run flat tire support body, and a run flat tire on which the run flat tire support body is fixedly mounted. The run flat tire support body (14) enabling a reduction in weight and the suppression of the wear of the outer surface thereof by the sliding thereof on the inner surface of a tire when the tire runs in a run flat state comprises a base material part (13) having an inner diameter allowing the support body to be fitted to a rim (16) and formed of a resin foam body of 0.3 to 0.9 g/cm3 in density, a reinforcement part (15) installe d on the inner peripheral part of the base material part (13), and a non-foam resin outer layer (11) covering at least the outer peripheral surface of the base material part (13).
