A tire consisting of a tread, two exterior sidewalls, and a plurality of interior support walls mounted to a rim and/or a run-flat support ring which provides for at least three pressure zones inside the tire. These differing zones provide multiple run-flat stages reducing the likelihood of complete pressure loss when the tire is punctured. These pressure zones also provide for the contact patch to be adjusted to the current driving conditions. When mounted to a vehicle where camber changes during cornering, these differing air zones provide for an extended contact patch during cornering by exchanging air pressure between the inside shoulder and the outside shoulder of the tire.
