What PSI are you all running offroading in your beadlock wheels?

I’ve got a fresh set of 37s on some KMC beadlocks and ready to take them out, but need some advice.

5, but it depends on your tire. One with a strong sidewall will need less pressure. Weaker walls will require a little bit more.
Wow, really?!

I got nitto ridge grapplers.

10psi would be a good starting point. I run my Yokohama MT G003 from 8-12 depending on the terrain. I kept them at 12 last time out for a little more axle clearance.

I have those same tires, 37/12.50/17 on DL bead locks. I run around 10-12 if I’m on a long stretch of a sugar sand trail. I run them 30 warm for DD.

You might be surprised at how little drop you get at 12 PSI. See my https://bt39.com/ and enter you weight per wheel, tire and rim size. Experience is better than calculations, but I show dynamic load and you don't want to pinch the tire when bumping.

I talked to a Boeing engineer years ago and he told me the DUKW's were designed to drop to 5 PSI in soft sand.
