New honeycomb tire is 'bulletproof'

The University of Wisconsin-Madison and a Wausau, Wis., company have come up with a 37-inch, bullet- and a bomb-proof Humvee tire based on a polymeric web so cool looking there's no need for hub caps.

Resilient Technologies and Wisconsin-Madison's Polymer Engineering Center are creating a "non-pneumatic tire" (no air required) that will support the weight of add-on armor, survive an IED attack, and still make a 50 mph getaway. It's basically a round honeycomb wrapped with a thick, black tread.

The military wants an alternative to the current Humvee "run flat" tires, which despite the name, still need a minimal amount of air pressure to roll and can leave troops stranded after being shot or blown out.
