<p>A two part run-flat device (13) for fitting on the outer circumference of a wheel (11) inside an inflatable tyre (12). The device (13) comprising a first part in the form of an annular ring (14) made up of a plurality (preferably three) of arcuate segments (15) that sits on the outer circumference of a second part comprising a sleeve (16). The segments are interconnected at each end by clamping means (23, 23a, 23b, 28, 29, 35) equally spaced around the ring that imparts to each segment (15) a circumferential clamping force and an axial clamping force to urge the segments circumferentially and axially towards each other. The inner sleeve (16) is shaped and dimensioned to fit on the rim of a metal wheel (11). In use when the tyre deflates and contacts the outer circumference of the segments (15), the segments (15) rotate relative to the inner ring (16).</p> |
