I run my G614's at 105 and use a TireMinder system to monitor them. I had my rig weighed at the rally ...year before last. They recommended 60 psi for the front tires and 80 for the rear...when towing. I have a 2011 Dodge 2500 4x and when NOT towing it rides very hard. In this regard, I carry a CO2 air system with me which allows me...when not towing... to reduce the rear tires to 45 psi for a more comfortable ride...and then increase the pressure using the CO2 air system to 80 psi ...before we tow again. To increase the pressure from 45 to 80 psi takes 4 minutes per tire.
