Resilient Technologies, a Wisconsin-based company, has developed the non-pneumatic or airless tire (NPT) as part of a four-year, $18 million project with the U.S. Department of Defense and the University of Wisconsin-Madison. Tires are commonly known to be a Humvee's weakest point. The NPT was developed to be used on heavy-grade military vehicles such as Humvees to help get troops out of harm’s way.
Resilient Technologies won’t release specific information regarding the polymers and other materials used to make its airless tires, but we do know that the honeycomb tires are built to handle a maximum load of 3.850 pounds (1,746kg). The NPT is designed to withstand the impact of a roadside landmine or small arms attack and will continue to roll along even if up to 30 percent of the tire’s honeycomb structure is estroyed. The airless tire is currently being tested on a Wausau-based National Guard Humvee.
