Good PSI

Hey guys, got the lift put in this past weekend. What is a good ON-ROAD PSI for a set of 265/70/17 Hankook DynaPro's? I have them aired to 36PSI each. Just wondering what you all run?

I got this from another thread on the forum.
Draw a line across your tire tread with chalk. Then, drive a few feet until some of the chalk is worn away. The chalk line should be worn away evenly over the length if your pressure is correct. If there is more worn in the center of the tread, you are over inflated. More worn on the outside portions, you are under inflated.
I tried it on my 265/70 17 silent armours and my ideal pressure is about 38psi.
