Truck tire pressure.

Recommended cold PSI is 60 front & 65 rear. They are Michelin 275/65/20 load range E on a 2017 F250 Power Stroke. Should I increase the pressure when towing my 39' toy hauler (Triton by Voltage)?

that is a big trailer, and if you have gear in it, its heavy.
if your truck is not a dually, increase the rear pressure to max tire pressure..... manufactures rate the vehicle as it is delivered from the factory, and if the buyer adds a load, modifies the vehicle, or installs different tires than what came as OEM, its up to the buyer to figure out what has to be done to find the right balance again..

I run michelins also but the max pressure for the model of tire I have is 80psi... I keep them fully inflated and they wear nice and I get good life from them.
an under inflated tire causes heat. and heat is the worst enemy of tires.
a tire that gets punctured can be repaired many times, but tires that overheat have to be replaced every time...

trailer tire failures (blowouts) are common, but its seldom the fault of the tire, but because it didnt have enough pressure in it to keep it from over flexing, and overheating....
