Resilient Technologies LLC, acquired by Polaris Industries Inc in October 2012, is providing research and development into the creation of a non-pneumatic tire for use on heavy-grade military vehicles, such as Humvees. In many situations in Iraq, tires have proven to be weak links in Humvees that enemies target with improvised explosive devices (IEDs). Although Humvee tires are now outfitted with run-flat inserts,an airless tire that's better at carrying heavier loads and can quickly move soldiers out of harm's way would be a major upgrade. Resilient has developed a "non-pneumatic tire" (NPT) technology, called that because it doesn't require air. Resilientâs design relies on a precise pattern of six-sided cells that are arranged, like a honeycomb, in a way that best mimics the âride feelâ of pneumatic tires. Aside from its strength, the design allows shrapnel and high-caliber bullets to pass through the tire. During testing, the tire has continued to run well - losing only a small percentage of performance - with much of the webbing removed. Airless tires have been around for a long time, but have had major drawbacks, such as bumpy rides and overheating. Resilient Technologies' prototype dissipates heat and is flexible enough to support the heavy Humvee loads while providing a relatively smooth ride with its honeycomb geometry design. The tire has potential for virtually any vehicle where a flat tire causes significant headaches, including all-terrain vehicles, agricultural machinery, mining equipment and construction equipment. The passenger automobile industry may be on the horizon as
