Tow Vehicle Tire Pressure
Do others increase / decrease the tire pressure in their tow vehicle when they are pulling the trailer? My truck specs say 35 psi for all 4 tires, but nothing about adjusting when towing. I'm thin...

It has been said that a safe bet is to use the door sticker for min psi number, and the tire sidewall for max. Sometime, like on P tires, it's the same number.
One of our trucks is a Ford F350 dually. These are LR E tires, 80 psi max. The door sticker says 75 front, 60 rear. That's what I have run for the last 13 years in them. This is the second set of tires, the first set aged out at 10 years with plenty of tread remaining. Almost all the miles have been towing either the large GN horse trailer or my equipment trailer loaded with Bobcat or other heavy stuff. Point is, in my case, running the door sticker recco has and still does work well. All pressures set cold, before leaving the barn, and never readjusted during the run.
As always, your mileage, pressures, habits and beliefs probably will vary.
