Abstract
A tire/wheel assembly includes a wheel having a rim, a pneumatic tire fitted to the rim of the wheel and a run-flat support member, the pneumatic tire having a tread surface and a hollow space, the tread surface having circumferential grooves extending in a circumferential direction of the tire, the run-flat support member being disposed in the hollow space of the pneumatic tire and having an annular shell and elastic rings, the annular shell comprising a support surface formed radially outward having a convexly curved surface portion with an annular apical line or face and two leg portions formed radially inward, the elastic rings supporting the two leg portions on the rim. The apical line or apical face of the convexly curved surface portion is offset in a direction of a center axis of rotation of the wheel so as not to be located in a position corresponding to the circumferential grooves when viewed from a radial direction of the wheel.
