Fat and Plus size tyres were popularised on bikes built for going places. Grip and float are the main parameters wanted there.
It may simply be there are better options for trail centres, especially if you have full suspension.
Epicyclic - I think you are right. They are fine for some stuff but unless the pressure experiments work out they simply add nothing to my rides

I've got one of these tyre pressure gauges, and it works a treat.

I nearly always ride in ECO mode as I find that assistance level great. Even in that mode I can feel in loose muddy single track the front wanting to push wide.
Hope you get this issue sorted and give us an update as to what worked for you.
Pressure gauge ordered. Updates to follow
I did run them at 15psi front and 12 psi rear for one ride.
That wants to be the other way round... try 12 front and 15 rear
Apparently a few psi makes or breaks the ride.
I know it most likely makes me a luddite, but it's the above that means I'm out. I understand some folk enjoy working out such levels of details, and I get it. But it's not something I aspire to do. I know all things bring some compromises and some advantages, but I'm more concerned about the smile I get from biking than my wheel size, and I think if I was fussing over a couple of psi that could ruin my ride I would give up. I'll leave this one to the innovators, as I'm sure nailing that tyre pressure will bring it's own rewards and smiles,good luck.
It only takes one or two rides to suss out correct pressure?
Lock everything out and keep letting a bit out 'till everything smooths out.
Note pressure.
Keep letting air out 'till it goes squidgy.
Note pressure.
There you go, a working range of pressures you can experiment with.
Just the same as with any bike, surely?
2 or 3 psi difference seems like a very fine margin but you've got too look on it in percentage terms. Going from 12 to 15 is a 25% increase in tyre pressure. You'd expect any bike to handle differently. Personally, I run around 15 front and rear but don't actually bother to check very often. If it doesn't feel flat, I just ride it.
Okay - without a decent pressure gauge I dropped the tyre pressure until they felt softer than normal and squidged under my thumb pressure. No idea what the pressures are front or rear, just lower than 20 psi and lower, I think, that last time I ran them soft.
A) On the road they felt a bit soft but didn't seem to squirm that much.
B) On the climbs they seemed to grip a bit more which was nice
C) On the descents there was some flex in the sidewalls but not enough to feel uncontrolled like it did last time.
Enjoyed the ride and just checked my Strava recording and it is splattered with PRs. Not that amazing as I wiped all my riding history when I got the eBike but faster on the descents which is encouraging.
