Bubblin’

inflated to spec to seat bead (38psi) turn around to drink coffee for 10 seconds it’s bubbling

I’ve set up a lot of tubeless tires before, never had this happen. Is it possible I was slightly over psi and fucked this thing up? I don’t have a digital pump so just went a hair under 40, wondering if my pump gauge is just off.

I deflated, let it sit for a while, put some sealant in and went up to 20, and the bubble is still there.

Any remedy for this other than getting a new tire?
