You could always do the chalk test. Run a nice thick chalk line accross the tire. Drive it straight down a level road for a couple of rotations. If the chalk is worn off all the way accross you are either good or low. If the chalk isn't worn off the sides, you are probably over-inflated. I run my 35 1250 Super Swamper SSR radials at 35psi on the road for the best response and mpg but I haven't done the chalk test, I bet i am over-inflated. I get alot of tread noise at lower pressures and more vibration.

The 60psi max that you are seeing is probably for carrying a load/towing. Look around there might be another psi rating on there that is some where like 30-40psi.
My street tires usually average from 32-35psi depending on what brand/type of tire I'm running at the time.
My wheeling tires are 36" swappers and I run them at about 20-25psi on the road to and from the trail head.
