OK, so the tire is solid foam

That was tried multiple times in the past and it doesn't work well. There's no reason to expect this attempt to be any more successful. A single component tire will never provide the performance of a multi-component tire, where each component is optimized for its function. You end up with a tire with high rolling resistance, poor wear characteristics and poor traction.

Like I said before, go ahead and buy a pair, then you can tell us how bad they really are. ;-)

Cavil on Brian

Is your commuter a "performance" bike?

"A single component tire will never provide the performance of a multi-component tire"

Anyone here care to report on those newfangled "tubeless" tires?

oh, wait, 700x30

Just janking jour chain, all in fun

If the solid foam tires ride like regular ones with thorn proof tubes they're doomed.

Didn't the ones in the late '70s have a profile like an ogee?

Last time I checked, oxygen is a pretty stable gas too. The problem with nitrogen, or any other relatively low molecular weight gas, is that it WILL permeate through anything that is rubber-like. Even if there were a polyvinylidene chloride layer (like in the old Saran wrap) it would still be permeable enough that if the tire is relying on gas pressure it would go flat in any reasonable time (months). Alternatively if the tire is rigid enough to not need gas pressure, and the N2 is just in there to reduce oxidation of the plastic (not a bad idea) we all know what the thing is going to ride like.

If you read their website FAQ...

...they're indicating that the N2 is supposed to serve the same purpose as the air in a pneumatic tire. There's also a bizarre sounding explanation of the air rolling around in a pneumatic tire, but not in the Nexo, so the latter takes more effort to get rolling. Like a lot of their other statements, this sounds rather dubious.

Fail

If they're relying on N2 for tire pressure, they're heading for a fall. It WILL permeate out, just like the air in our tires does now (it's 79% N2). This thing is looking more and more like a collection of misinformation rather than science.

Exactly

That's what I've been trying to point out all along. This is just the same old junk, wrapped in a bunch of misinformation and outright lies.
