700x38 isn't typically used on 29er MTBs, but I think somewhere in the low 50s for your rear tire is a good place to start. Front tire 5-10 psi less depending on your posture & weight distribution on the bike.

I actually thought BF had a cyclocross forum, but I don't see one. Perhaps the road forum? Surely some of those lycra-wearing folks have moved on to gravel / CX bikes with tires this size. My CX bike has 32mm tires that I was given, and I'm foolishly riding them. The bike can clear 45mm tires, so I really should be riding wider. 32s are brutal on gravel since I have to run at least 60 psi to keep the rear tire off the rim.
