Jargo432, In my 32 mm tires I generally run between 65 PSI to 80 PSI, most often at 75 PSI. I weigh 180 lb. and I only used 80 PSI on the rear when it was heavily loaded. I don't know positively that pressure was absolutely needed, but is part of my range.

PS Some tires may show BAR along with, or instead of a PSI rating. One BAR is ~14.5 PSI.
