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...

I keep the wifes '16 1500 chevy crew cab short bed with P255/75-17 at 38psi in front towing a 10k trailer or empty. The door tag also says 35 psi all around.
...and the rears at max sidewall 44 psi when towing and 32 psi when empty. The tires have 45k+ miles now and should make another 10k before I retire them before hard winter sets in.
I use the chalk line method on all my trucks to find the best ride and best long term wear for each truck (1500 chevy....2500 Dodge/Cummmins....and a '98 3500 DRW crew cab 4wd 454 gazz hogg.
