The honeycomb design allows bullets and shrapnel to move through the tyre without disabling it. The non-pneumatic tyre (NPT) will continue to run even if a substantial portion of the honeycomb cells have been disabled

Cooper Tire and Rubber Company has developed a non-pneumatic (airless) prototype tyre in collaboration with Resilient Technologies, designed to reduce the number of military personnel stranded in war-zones due to flat tyrpes caused by gunfire and shrapnel.

The airless tyre abandons the traditional tyre and rim design for a structure comprised of a unique rim, honeycomb and tread package, thereby eliminating the need for the cavity that typically retains air for a traditional tyre. The honeycomb design allows bullets and shrapnel to move through the tyre without disabling it. The non-pneumatic tyre (NPT) will continue to run even if a substantial portion of the honeycomb cells have been disabled.
