38s and psi

I have a set of 38x15.5r20s on the way and should be here Friday. I bought a set of 20x12s a while back and Im gonna mount the tires to them, I CANT WAIT!! Are any of you guys out there running this set up? If so what psi are you running in your tires? I dont want to have to put them on drive home the tires be hot and have to wait for them to cool down and do the ol' chaulk line test. I wanna drive it and show it off I would like to be able to tell the guys what to put in them and then drive for awhile thanks

I was running 60 psi in my 37's cause I tow quite often, but I dropped them down to 40 psi so it rides better this time of year.

Thanks. I had 36x14.5r16s and I was running 55 in the front and 50 in the rears and that was perfect. It took me a while to get them just right as I'm over **** about my tire psi brcause lets face it tires are not cheap. I laugh most of the time when guys need new tires and don't want to spend $1000 on them. I stil have my snow tires on the truck and it's been in the 70s and almost 80s here and I feel like an idiot driving around ony 315/75r16 still
