Default Just mounted new tires. Help with what PSI to run

I just mounted my 37x13.50x17 Super Swamper M16 on 17x8 aluminum wheels. Jeep is an 08 unlimited with minimal weight adders. The tires have a 10 ply tread and 3 ply sidewall. They also state they are load range E supporting a load of 4050 pounds at 65 PSI. Seems like a tank of a tire, but believe it or not, only weighs in at 78 pounds each. Currently running 32 PSI, but am only getting contact in center of tire. What do you think I should set the PSI to?

Yeah thats where Im at right now. Just seems to be crowning a bit. I know, I know, thats what you get with a poor mans beadlock running 13.50's on an 8" rim. Just seems like I should go down to 30PSI or so just to spread it out a bit.

I run my 37 toyos which are an E tire at 25lbs. They wear great at 25 and ride well. Chalk test will figure it out for you.

Kinda off subject, but I'm looking at getting m-16's in the same size. Not alot of pics mounted on jk's. Can you post a few pictures for me to see? How do you like them?
