I have some WTB i25 rims with high roller 2 on the rear and it's so tight!
I have broken three tyre levers. The only way to get them on is to use the metal one's I have.
Also, I recently put a HR2 on the rear and inflated to 50psi to seat it properly. 5 minutes later it made a loud bang and came off the rim getting sealant all over me.
1. Can the rims get knackered allowing leaks or bad seating of beads?
2. Should I alway pry the tyre on with both beads off the rim to allow for more wiggle room?
1) some rim/tyre combo's are a nightmare. If you struggle that much in the workshop imagine what it'll be like in the rain on a January Tuesday night when you have to try and get a tube in there...
2) 50Psi is quite a lot for an mtb tubeless rim I'm not over surprised it blew off (missus). I always inspect tyres as soon as they pop onto the bead to make sure they're seated evenly - they can end up slightly askew occasionally.
3) always drop the bead as far into the well as you can when fitting a tyre, tubed or tubeless.

God yes. I've checked the rota and it's my day to be the dick... So, I have WTB i25s and I have assorted maxxis tubeless tyres and they're absolutely fine. No tighter than anything else. It's all about getting the tyre right into the valley of the rim, that's where the slackness comes from, it's harder to do with some rims than others (older rims tended to be pretty deep there so it was simpler) You need to not just get it off the bead but right into the middle.
As for popping off, the trouble is that once it's happened once it'll tend to knacker the tyre's bead. You might be lucky though. You can flatspot a rim enough for a tyre to pop off but you have to seriously work at it, you'd be able to see damage easily.

This is why I took my Nano 40s off my Escapade. Total pain to fit, didn't fancy it doing it trailside miles from home.... 🙁
I too had no bother with an Ardent on WTB i25s recently - was a thumbs only job. Bonty tyres were a little bit tighter.
Broke 3 levers getting bontys onto arch ex though, so it's no guarantee.
I would tell you to wait until you'd popped it onto the rim before you deflate and put the sealant in, but I guess you know that one already now. 🙂
