There’s nothing more frustrating as a driver than the shock and hassle involved in pulling to the side of the road to fix a suddenly punctured tire. Squatting on the curb and finagling your car’s stock tire jack while cars zip past inches from your body is hardly any one’s idea of a good time. Fortunately, and in collaboration with Polaris Defense, the US Military has been perfecting new tire technology that is neither pressurized nor made of rubber.
These non-pneumatic tires (NPTs) are made of closed-cell polyurethane foam whose webbed design allows for greater flexibility and durability against a variety of off-road terrain. Jason Difuccia, a spokesperson for Polaris, says, “The load is carried in tension across the top of the wheel. The bottom of the wheel is designed to give in to obstacles like rocks, curbs, and other terrain.”
Although these new tires are specifically designed for military and off-road recreational vehicles, let’s hope this technology will eventually influence the redesign of car tires.
