Tire Pressure?
2022 Gulfstream Conquest 6280 on a Ford E350 chassis. The tire pressure recommended on the driver door tag says 75 psi front and 65 psi rear (drw). Last year I had a young tire tech tell me that they ...

first thing you need to do is weigh the rig ready for the road. Gear on board, fresh water and the like.
Then go to the tire manufacturer website and get the inflation chart.
Inflate the tires according to that.
I run five pounds over chart indicated pressure!
Winner,Winner, Winner! Ding, Ding, Ding! It is just that simple. :S
For the record I have 24' E-350 Class C, GVWR 11,500# and run at or very near that often towing a 2,500# Cargo trailer. 60 psi for the fronts and 65 for the rears gives me a 5 - 10 percent fudge factor and a very smooth /stable ride.
The folks who place the door tags have no clue how you are going to load/use your coach. The kid who recommended 80 psi is an idiot as that will guaranty a horrible ride. Over inflating the fronts will make the steering loosey/goosey as it reduces the contact patch.
Opinions vary as to when but tires time out, often long before they wear out. Had a tire grenade doing $4,181 in damage {it blew the wheel well right up through the bottom the coach}. It was less than 6 years old and had been inspected by Discount tire the previous day, had 6/32" of tread, looked great and was aired for the load carried. I now replace my RV 's tires at no more than 5.5 years and yes I live in Arizona which is a "challenging" environment {to say the least} for tires.
Folks who actually use their RV's on a regular basis will often approach wearing them out {5.5 years for us is easily 40,000+ miles}. I just replaced all 4 of my duallies with Michelin Agillis Cross Climates {my front tires and spare are all Agillis CC's and just a little over 2 years old}.
As noted,... Opinions and YMMV.
