Truck Tire pressure

Hello to all, I am new to RVing and I have a question on the truck tire pressure. I just put on new Michelin LTX M/S2 275/65/20 tires on my 2013 Ram 1500 Bighorn. I will be towing a Jayco Jay FLight FB22 trailer. Can anyone give me some advise on tire pressure for the tow vehicle? The tire sidewall says that the max is 80PSI cold. What does everyone run in their trucks.

Thanks

What does the drivers door sticker say? I would run at the pressures recommended by the truck manufacture as long as it does not go higher than the max listed on your new tires.

... what he said.

My LT tires are at 80psi rear and 75psi front (80psi front gives VERY harsh ride).

I think e range tires get 80 psi and d range get 65. I'm sure you can tweak that a bit.

Go with the sticker in the door of the truck for tire pressures. Double check that your truck tires are the same size as recommended from the truck manufacturer.

I just put the same tire and size on my F250. Them tires were not cheap. The garage I purchased my tires from said to run what is on the door sticker as long as it is stock size and mine is. The tires you got are 70,000 mile tires right, not that we will get that towing.

Yeah, they are the 70,000 mile tires. the reason that I ask this question is because the tires that came off of the truck were the stock tires that came with the truck and the size on those were 265/60/20 so the Michelins are a bigger size and I don't know if I should go with what the door sticker says.
