Abstract
A runflat device, and a method of fitting a runflat device. The runflat device can include a chain of segments which is flexible enough to be manipulated for fitting, while also being laterally stable to ensure correct positioning and to avoid misalignment when tightening onto a wheel. The fitting method initially expands the runflat device within the cavity of the tyre, retaining the runflat device securely in place against the inside of the tyre's tread area. This advantageously leaves the beads of the tyre unobstructed for fitting to a wheel.

A method of fitting a runflat device comprising a flexible body having two ends, the method comprising the steps of:
- coiling the flexible body to a diameter smaller than an interior diameter of a tyre;
- inserting the coiled body into a cavity of the tyre;
- uncoiling the body within the tyre cavity and connecting the ends of the body with an adjustable connection means, thereby forming a ring;
- and
- expanding the ring with the adjustable connection means, thereby locating the ring against an inside of a tread area of the tyre.
