Recently had our coach weighed. We are at 6,700 lbs (3350 per tire) front and 12,180 lbs (3350 per tire) rear when fully loaded. Tires are Goodyear G670. Using the tire pressure chart from Goodyear it...

Just right is what you really want, however it is difficult to obtain. You need a 4 corner weigh, then set your pressures to the heavier corner for the front and for the rear. Under inflation is a killer, in many ways. Tires overheat, sidewalls flex way beyond design, handling downgrades and ride can worsen. Now over inflating has its own issues, hard ride, odd tread wear among others.
So get weighed with your rig as full as you use it, not empty. Get each corner weighed and then do the research. And when you are done, remember tire pressure is not a constant! Monitor it! If you inflate in June, you will not be correct in December! Check you tire pressure each trip, or possibly get a TPMS system and set it up. It could save more than a flat tire.
