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...

When you air them up to their max, remember to account for heat. Aired mine to 77 PSI (rated for 80 PSI max). Coming back from a camping trip the display showed they were 88 PSI. Pulled over and lowered to 80 PSI. Account for heat!!!
You, DON'T account for heat. The engineers have already done that. You always set them cold. If they are at correct pressure, the heat buildup is normal. Now, if one gets low that will create excess heat that can raise the pressure to the point of a blowout.
