The Stovebolt Site Forums The Parking Lot Big Bolts Recommendation for minimum tire pressure

All you have to do is look at your owners manual. Mine says 40 PSI for the front and 55 PSI for the rear on my 46 2 ton. All ways refer to the factory specs. I've ran 20 PSI in some rock hard tires on the rear for years with cracks so big you could put your finger in, never had a issue.
