Its a completely pointless question - hence my 8psi answer.
It's like asking how much pressure do you run in your rear shock (0 in my case)? or what saddle is the most comfortable or pretty much any other set up question..... It's all irrelevant, or rather only relevant to the person answering....
"Am I the only person that squeezes the sidewalls, thinks that is about right then rides?"
No, that's what I do. I have 2 track pumps and they both give a different reading anyway. Quick squidge test is the way. If they need a little added I err on the side of caution knowing I can let a little out if the ride is a little skittish™.
The correct answer is lower than 70, higher than 3 😀

What colour shall I paint the bathroom? What shall I eat when I get home? Which way should I ride home? How should I fill the next ten minutes?
Whilst i agree it is a very subjective question and depends on a lot of variables, sometimes people struggle with trusting their own judgement so a bit of benchmarking can help.
So in that spirit...

Mostly Peak riding.

But inst that the point - there no details, without the details and by asking what do you do? The op ends up with tons of useless information, and is no better than before asking the question.
It's like almost any question asked on you tube based FB group - absolutely pointless. I highly suspect that the OP is a genius with the title question - taking the pis?

It's not useless, though, is it?
I haven't collated (or even read) read all the replies, but they're a straw poll of what riders in the UK are doing at the moment. I'd guess that anyone outside of the relatively narrow 18-28psi window is probably a bit of an outlier. Within that window, adjust according to rider weight, finesse, tyres and terrain. Simple?
Or you could just moan about it?

30mm internal Spank Oozy wheel has removed most concerns about burping a tyre, and eliminates the need for the air to keep the tyre the correct shape, so assuming "support" isnt really an issue, i tend to go as low as i can get away with without clattering around on the rim.
which is about 20pis F&R, at 95kg ish wet.
Im still always tempted to run them a bit harder on bigger rides, to try and eek out some reduction in rolling reistance, but always regret it pinballing around on rocks and sliding around in the mud.
sounds a bit excessive obsessive there frank.

I have been running 20 rear (2.35-2.6) and 18 front (2.5-2.6) on my 29 FS, I’m 71 kg. That feels spot on without squirming and no rim strikes. However, I’ve just knackered my third or fourth tyre in about five months so I’m guessing I need more pressure, which doesn’t feel as good, but will work out cheaper. Latest tyre was a 1.3 kg Vee Snap which is a pretty robust tyre, it did what all the tyres did, sidewall in one spot lost its integrity, bulged out and wouldn’t seal. I blame lockdown, before that, I wasn’t brave enough to do bigger drops. Clearly not big by many riders standards, but big enough to keep me changing tyres that are barely worn.
About 100kg..

Don't ride anywhere rocky really, just a bit rooty but I've managed to learn to pick my lines on them.
