Tried everything, even nearly boiling water and finally got it off.
Can't get the tyre back on though. I've even tried different tyres and broke 3 re-Inforced levers in the process. It's like the wheel has expanded by 5mm.
There is no slack at any point of the tyre when it's in the centre of the rim.
Can't go wrong with a Joe Blow track pump. No, should never be liquid coming out of nipples. Re-do your tubeless set up.
