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 REALLY sucks when heavy duty truck owners respond with heavy duty specific info, when they should know that this is NOT about a heavy duty tow vehicle.
In the past, when I've run D & E rated tires on my half ton pickups, I ran them near the OEM recommendations (35 - 40 PSI) for daily driving, and they performed fine. I found that no more than 55 PSI was ever needed for even the heaviest loading (well above GVWR). Now, I've seen the light, and run the wimpy P rated tires, and just air them to max when towing. Otherwise they're at the OEM recommendation.
