Tire pressure
#21
I run 65psi on the front right (battery is heavy), 55psi front left(I'm heavy), 22psi rear right(it just seems right), and 29.3psi on the rear left(because I can).
Please, NOBODY use this method!
No, seriously, I've run 32psi on all 4 since I bought it, and the tires seem to be wearing fine and ride is nice.

These tire pressure threads are dumb anyway.
Tire pressure depends on too many variables to say what someone should run, unless they have a stock disco running stock tires. In which case you can just look in the manual, which, incidentally, lists substantially different pressure front and rear.
Factors that affect required tire pressure for street use:
Vehicle weight (total added weight modifications/accessories plus weight of passengers, cargo, etc.)
Tire brand
Tire size
Tire construction
Tread type
One way to know for sure is to weigh your vehicle and call the tire manufacturer, give them the tire model number (all tires have a model/item number) and they will tell you.
Another way is to experiment to see what pressure gives you an even tread pattern. Chalk the tread and roll forward. Check the pattern on the pavement, adjust as needed.
A third way is to use an infrared thermometer to find at what pressure you have an even tread temp across the tread when driving, adjusting the pressure to attain that.
The forth way, if you don't really care about it, is to ask on a forum.

Here is some good information, and it confirms what Tom says, there is no correct answer without some investigation.

There are quite a few links in that thread to technical information and math that I'm too lazy to do.

I normally run 32 all around, on most of my cars for that matter.
Today, I decided to try 38 all around. DANG, it's like driving Mexican Jumping Beans down the road. It's SO jumpy, bumpy, and not fun... Going back to 32 since I was not experiencing any wear issues anyways. I also had a very nice smooth ride before.
BTW: I'm running Toyo Open Country AT's, Stock 18" Size.
