A run-flat tyre has three separately inflatable annular pressurised chambers A,B,C and a valve (4, Fig 1) capable of being rotated to any of three positions, each of which will allow a specific pressurised chamber to be inflated. The tyre also features a number of non-pressurised compartments (37, Fig 3) between the central pressurised chamber and the crown of the tyre. The central pressurised chamber may be strengthened against punctures by layers of reinforced composite material 32, 34.
