A dual compartment tire has a primary air compartment and a secondary air compartment that is internal to the primary air compartment. During ordinary travel, the primary air compartment is in contact with the road surface, with the secondary air compartment constituting an integral spare tire in the event of a flattening of the primary air compartment. Each of the primary and secondary air compartments is bounded by an exterior surface. In contrast to prior art dual compartment tires, the exterior surface of the secondary air compartment is relatively thicker than the exterior surface of the primary air compartment.
