What would be a good air down pressure for stock Rubicon rims for off road? Running 33" Federal Couragia M/T's?
Tire pressure on Rubicon rims?

Rims or tires? Lots of guys run different pressures. If you are on easy trails with not a lot of obstacles, 20 psi is fine.

I normally run 20psi if I'm running local trails without to many rocks but if I'm doing more serious trails I'll drop them to 10psi.

Ive ran my 35x12.50 at 12-13 psi numerous times without issue

I've run as low as 8psi without dramas on stock rims with 33s. You'd need to be pretty unlucky to lose a bead unless you had a big load on the sidewall.

If you pop the bead, you were too low.
Now that my smartass answer is out of the way, your question has no definite answer per say. However, a lot of people (myself included) have dropped to about 10 PSI and been fine. The different terrain can affect what pressure you need. If you get on some side hills a lot then you may need a higher pressure as the weight of the jeep will want to make the tire roll more and possibly pop it off the bead. Etc.

Like previous said so many factors. The weight of the rig and everything also play a roll. My dad has a buddy with a toyota with steel wheels and goes so low that i have actually seen the tire wrap over the wheel and not pop a bead. Just depends on all kinds of things.

I went to 5 psi on my 35x12.50 KM2 tires on a snow run last winter on stock Rubi wheels. Tires looked flat when the weight shifted to one side. I wouldn't go this low is the rocks, and usually run 18 psi in the rocks. I would run lower in the rocks if the sidewall was stiffer, but loose too much clearance at 10 psi on a KM2...
