2. Run your rear tires at the Load E maximum of 80 lbs..
Common mis conception is to run tires at sidewall max inflation pressure. This creates a harsh ride and poor tire wear. There is a magic number for every circumstance based on weight the tires are carrying, and it isn't the max. On my 10,200 lb Max Gross View with 225/75R16 E rated tires, the number is about 62 lbs.
Scroll down to page 21 of the PDF linked to for LT tire inflation ratings for 16 inch wheels, both single and dual. You have to know the load on the axle to read the charts, and this is for Michelin tires, but I suspect that other brands will not vary much from this.

I believe the recommended pressure is printed on a placard inside the driver's door on most vehicles. Of course as you point out, circumstances dictate...
