I had the same problem with stretched beads on a pair of Snoqualmie Pass tires. Initially they sealed fine, but when I took one off and remounted it, I couldn't air it up, even with a compressor. I won't run Rene Herse tires tubeless again. Also had trouble with sealant bleeding through the sidewalls and a bubble forming in the tread. That tire they replaced under warranty.

I guess I shouldn't be surprised that these tires don't work well tubeless. They are light weight, performance tires. It's no wonder they have weak tire beads and porous sidewalls. I'm sure they work well with tubes.
