My rig is very similar to your (see SIG). My rig weighs 15460 lbs. loaded for a typical trip, 4300 front axle, 3940 rear axle, and 7320 on the trailer tandems. According to the Goodyear inflation charts I carry, my tires (265/70-17 truck, 225/75-15 trailer) need just 40 PSI to support this weight. I was taught to run a minimum of 10 PSI above the minimum so I routinely run 50 PSI front and rear on the truck. I consider 50 PSI the absolute minimum for the trailer and usually run 55-60.
