I'm trying to decide if 32mm is big enough that I would feel comfortable running it tubeless. Like I said above (only poorly) I run 38mm tubeless without issue. Jan Heine says that 60psi is the safe limit for tubeless, and that makes sense to me. That's pretty close to the pressure I run my tires. I would probably be happier with some margin though. I run the 38mm tires at about 40psi.
