Airless Tire Promises Grace Under Pressure for Soldiers

To keep troops from being stranded and easily ambushed on the battlefield, the Army is working with researchers to develop tires for their Humvees that can better withstand roadside attacks. One such design comes from Resilient Technologies, LLC, based in Wausau, Wis., and the University of Wisconsinâ??Madison’s Polymer Engineering Center. With a four-year, $18-million grant from the Pentagon, Resilient is working to create a “non-pneumatic tire” (NPT) technology, called that because it doesn’t require air.
