All the "XX.5" tubeless rims have a very steep angle flange at the bead area, and a deep drop center. A straight bead tire goes onto the rim pretty easily, but unless a tube is used, it's very difficult to get the tire to hold air. One of the "Cheetah" tanks can blow enough of an air blast into the tire to get it to stick to the rim, but I've never seen one survive to normal inflation pressure without breaking the bead wires or blowing the tire off the rim if it's slightly misaligned. Deadly dangerous when it lets go!
