I'm not sure you'd be able to go to tubeless tires without other mods, but you should be able to run tubed tires. I think one of the big "misses" with the ERT system is the tires really aren't that supple or desirable, so one of the draws to running tubeless (a ride that feels light and supple) is not there with this system. I also have heard that it's difficult to repair on the side of the road if you have need to -- because of that separate bladder wall.

As with most "systems", there are pros and cons to the proprietary one that Giant have come up with. Without popular support in the aftermarket, the only real ERT choices are the cheap-but-costly OEM tires, which really limits the use for this specific technology.
