I'm curious what other folks are doing pressure-wise.
I'm fairly lightweight (70kg, possibly after lunch? With back pack and water, who knows? I usually carry extra tools, etc...), and run 2.6" 27.5/650b tires.
Rear is around 20psi, but it's tubeless so I generally catch it once it's slipped down to 15 or 17 after a few weeks :). I've just realized I'm not even sure what the tire is, but it's a maxxis brand, so probably actually 2.4" wide compared to most other companies - not much clearance on my Intense Recluse
My front is usually about 18psi, on a specialized 2.6" somethingorother (pretty sure it's not a butcher)

If you don't hear your rim hitting the rocks in the trail, you are probably fine going down. If you go up a lot, you can try higher pressure and see how that feels as it will lower rolling resistance.
Then find a happy medium depending on how much uphill va downhill you usually ride.
I'm about 80kg +water and found 24psi to work best for me.

Depends. I have a few setups I run.
Trail bike (Clash 2021) 27.5x2.4":
Jump/SS (Meta HT AM 2020) 27.5x2.8":
On trails, if it's really slick, I may drop 1-2psi for better traction. Obviously, if jumps are slick, I won't ride them.

About 35 psi on 27.5x2.2" Kenda Honey Badgers. I ride XC in an area with occasional lumpy basalt. It can be pinch flat hell with tubes. Even with tubeless I still worry about denting my rims at lower pressures.

i do around 30psi. i use tubes as tubeless is just hopeless on the terrain i am riding (tires develop long-ish slices after a few rides that no sealant could ever fix) due to there being sharp rock shards. tires are Continental crossking 29" 2.2. i weigh like 60 or so kg and my bike is like 20-23 (emtb)

Interesting! Such different conditions all round... Cheers!
