Went to the web site. Looks like right now they only make sizes for 18,19and 21in dirt bike sizes. If they work like claimed they'd be great for enduro, ISDT, desert racers and the like.
Flat tires are a real PITA when you are out in the boonies 75miles from nowhere.

I wish there was a practical, not too expensive, way to run without tubes on my S40. Tube type tires on a street bike don't make much sense nowadays IMO. I think even the spoked wheels on the newer Harleys are built for tubeless tires. Probably others that I don't know about too.
