My truck tires are - Bridgestone Duravis LT265/70/R17 Rated "E". Weight rating is 3135 lbs and max tires pressure is 80lbs. The sticker on the truck door states the tire pressure should be Front - 60 lbs and Back - 72 lbs. When driving the truck without the 5th wheel I use 60lbs in the front and 72 lbs in the back. When I hook up the 5th wheel with a hitch pin dry weight of 1965 lbs should I be filling the tires to 80 lbs, or still use the 60 for the front and 72 for the back?

I'm kind of wondering about the 80 lbs max tire pressure. Is the 80 lbs suppose to be the cold tire pressure, or is that the max tire pressure when the tires are hot? I'm kind of wondering about this 80 lb tire pressure for my 5th wheel tires, because a tire shop guy told me to put in about 75 lbs in the 5th wheel tires and they will heat up to 80 lbs.

I would greatly appreciate input that will allow me to use the correct amount of air pressure so that I don't put my tires at risk of blowing out.

Thank you.
