We've been waiting for airless tires to hit the market ever since the concepts starting showing up a few years ago, and it looks like it's finally beginning. These TerrainArmor tires are being billed as capable of sustaining significant damage without loss of function and "eliminate the need for an on-vehicle spare," and have seen service on military vehicles for about a year now.
They're kinda funky looking, but we think they're brilliant, and need to start showing up on cars post-haste. In the mean time, to sate your desire, they're available on the Polaris Sportsman WV850 HO.
