Thanks again. I intend to ask Vaughn if building up the bed, whether with Gorilla or Stan's, might keep the bead in place absent air pressure, and the stick factor may also be a useful element.
If the Kojaks can't be run tubeless without forethought -- for example, having to check the tire every few days for pressure -- then I think I'll bail. I want tubeless, yes, but no worries tubeless.
