Polaris' latest ATV has airless tires that can withstand .50-caliber rounds

While the everyday driver relies on a set of pneumatic tires to get from A to B, tire companies like Michelin are doing valuable research and development into airless tires because they don't go flat. The Polaris ATV is designed after the same all-terrain vehicle Polaris rolled out to the military earlier this year. However, Polaris puts great stock in its tires, and hopes to see more consumer uptake in years to come. Originally designed by Wisconsin-based startup Resilient Technologies, the tires feature a durable honeycomb core bordered by a thick rubber tread.
