Pretty bastard hard....I inherited the 23mm when I bought the wheels, will change to 28/30mm once it's worn out. I did use a plastic lever, I realise that might stretch the bead. The tyre wasn't new, but it went completely flat and after I took it off there was a hole in the rim tape, so I re-taped, probably using Tesa that was too wide in hindsight - presumably that isn't catastrophic now?
Wide rims tape shouldn't be a problem, unless it's likely to push the tyres bead off the rims, I find a proper coverage work wonder allowing the tyres to "slide" on the tape until it hit the hook.
Maybe, it's certainly a learning curve after many years of tubes. I also realise that 23mm is fairly pointless to run tubeless, I wouldn't trust that low a pressure having dinged a rim on a pothole recently. But no punctures so far.
