摘要： Provided is a run-flat support body (1) for a pneumatic tire, in which an outer peripheral side of an annular shell (2) serves as a support surface for supporting an inner surface of the tire (T); an inner peripheral side of the annular shell (2) straddles in the form of a bifurcation; elastic rings (3) and (3) are attached respectively to two leg parts (2b) and (2b) of the annular shell (2); and the annular shell (2) is supported on a rim (Rm) of a wheel with the elastic rings (3) and (3). The elastic rings (3) and (3) are composed of a composite elastic material formed by compounding reinforcement fillers in an elastic material. Accordingly, compressive rigidity of the elastic rings in a radial direction of the tire is made larger than that of the unreinforced elastic rings in the tire radial direction, the unreinforced elastic rings being composed of a single elastic material in which the reinforcement fillers are not compounded. Moreover, bending rigidity of the elastic rings in an axial direction of the tire is made substantially equal to that of the unreinforced elastic rings in the tire axial direction, the unreinforced elastic rings being composed of a single elastic material in which the reinforcement fillers are not compounded.

摘要： Provided are a run-flat supporting body whose durability is enhanced while a large number of through holes are formed in an annular shell thereof, and a tire/wheel assembly. The run-flat supporting body (1) is configured of the annular shell (2) and elastic rings (3) and (3). The annular shell (2) works as a supporting surface on an outer peripheral side, and bifurcates into two leg portions on an inner peripheral side. In addition, the annular shell (2) is provided with a large number of the through holes (4) in wall surfaces thereof . The elastic rings (3) and (3) are attached respectively to the two leg portions of the annular shell (2). The run-flat supporting body 1 is supported on a rim of a wheel with the elastic rings (3) and (3). According to a configuration of the present invention, peripheries of the respective through holes (4) are thickened, residual stresses are applied to the peripheries of the respective through holes (4), or each through hole (4) is formed into an elliptic shape having the major axis in a circumferential direction.
