What air pressure do you run in your 35"s?

Load range C? D? E? Sidewall plys? Radial or bias? Military take-offs? Freeway or off road? Sand, rocks, or mud? High pressure generally = rough ride but good mileage. Low pressure = comfy ride but crappy gas mileage. Too many variables and not enough info in what you want.
If for the highway, do the chalk test as described above. If off road, as low as you can go without breaking a bead.
It all depends on what you have and what you want in a ride.
For what it's worth, I run ~34 PSI freeway and 12 PSI off road; BFG KM2 Load Range D. 34 PSI seems about right for OK mileage and not rattling my teeth. Lower than 12 PSI gets too close to break-a-bead territory if you don't have bead locks.
2 cents.

I run 30PSI on my Grabbers... If you really want to find the optimum pressure for your tires while out DD
, find a good, smooth paved surface and do the chalk test on all four tires. You'll find the optimum pressure depending on the chalk pattern you find on your tires. Chalk wear in the middle only - too much pressure. Chalk wear on the outside, too little pressure. Even chalk wear - just right!!!

I run 2 sets of 35's (1 summer, 1 winter), and both are wearing very evenly and ride well. I got advice from people that had run the same types of tires on a rig of similar weight, and then verified it with a chalk test. My tires now wear so evenly that when I go in for a "preventative maintenance" alignment/balancing/rotation, the manager of the tire shop comments to me about how my tires are wearing perfectly evenly.
Your best bet? Listen to the wise words of AZJeeper, and follow the chalk test as laid out by jezzalachis.
