We've known about airless tires for a while now here on Geekologie, but now the US military is getting involved and testing them sums of beaches out on some of their vehicles. But not their tanks -- they don't have any air to begin with, silly!
The advantages of airless tires are obvious: they can't be punctured and they never go flat. But it clearly takes a lot of science to get the proper material that can stand up to the pressure of a multi-ton military vehicle sitting on top of it.
Nice, military, but how about some REAL airless tires. I'm talking about hover wheels, bitches! I know that shit exists, we stole the technology from the aliens. GET OUT OF MY HEAD GOVERNMENT! Quick, somebody Reynolds Wrap me, STAT!
