The tyred wheel rim has >=1 circumferential band of magnetic rubber or plastic material on an inner surface, another similar surface moving in relation to the first when the tyre is flat; a magnetic liq. lubricant is held in position by the band to permit movement between the two surfaces while the flat tyre is being driven. The circumferential band is best placed at the inside of the tyre sidewall and/or its tread, it is a rubber contg barium ferrite and embedded in the tyre itself. The magnetic lubricant contains colloidal particles of Fe3O4. Lubricant cannot escape or require injection if the tyre is flat.
