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...

Yep, 1/2 ton GMC Sierra. Door sticker says 35 psi. I put E rated tires on that say max pressure 80 (due to towing trailer at times). If I air up tires to 45 psi unloaded (no trailer) it shakes the truck to death above 60 mph, but good with 35 psi. Weird.
Anyway, getting ready for a trip next weekend and in the past pumped up the rear tires to 45 psi when towing, but no science behind it. I looked up the tires and they 3,xxx at 80 psi.
