Patent number: 10358003Abstract: 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.
