Tire pressure - please confirm
Hi, I want to draw from your experience. My 2016 F150 tires are set at 39-42 lbs. They are filled with Nitrogen. The sticker on the door says 35 lbs. With the tires at approx. 40lbs, we find...

If the sticker on your truck says to inflate to 35psi, then at 35psi your tires would be capable of carrying what your truck is specified to do (GVWR, front and rear AWR).
In theory you could set them at 35 and forget about it.
When towing I do tend to increase the psi and then decrease it after the trip.
This is how I manage my pressure. The driving characteristics of a vehicle are engineered with the door jam pressure in mind; rollover, ABS, traction control, etc. I would be weary to overpressurize tires when not towing.
Having said that, I do increase to 39psi when towing. I noticed a slight shimmy (not sway) when I towed at 35 psi. It went away at a higher pressure.
The "shimmy" feels as if two people (one on each side of the truck bed) are pushing the bed back and forth ever so slightly? If so, I call it the "P rated wiggle" myself. We had that towing our ~7200lbs (920lb tw) tt, switched out to LT LR C's, and all was nice and stable!
Marcarolle,
If the truck is used mostly as a tv, I would probably just keep the tire pressure at the max sidewall pressure, or close to it. Do you have any "wiggle" or "shimmy" when towing at the pressure you use now? If not, then you are probably good to go. If so, then up the pressure 1-2lbs at a time until the "wiggle" is gone. BUT do not exceed the max sidewall pressure!!!!
Depending on how much sight seeing you do while camping, it may not be worth dropping the tire pressure back down for a few days. Just make sure you have a capable compressor/ tire pump to get the tires back up to proper towing pressure.
Good luck!
