A question from an Airstream owner.
I have a 2020 Ford F250 and an Airstream 33' Travel Trailer. I've read a lot of discussion about tire pressure, but nothing real current. What I mean is, the newer F250 door column states for these Michelin tires now, 60psi front and 65psi rear. The tires max at 80psi on the sidewall which was my experience with prior year F250's on the door column too, but the tech at the dealership said they've changed and that with normal driving you can run 80psi, but harsher ride and you'll run the "middles out of them."
On to the Airstream. All four tires are Michelin LT225/75R16, Load Range E. The Airstream sticker says 80psi for these tires. I went up to my local Dobbs Tire Dealer and he pulled up the Michelin chart for these tires, and said with a trailer weight on dual axles of between 7980lbs and 8600lbs, you could run the pressure between 60 -- 65psi. I asked if I would have a problem with tire heat or wear and he said no. I did put a 3" lift kit on the Airstream, so as to have better clearance at gas stations and various road conditions. The dealer puts in 80psi, but from time to time I get popped rivets, (if ride is the cause).
My question is this: With an approximately 8200lb trailer, 1300lb hitch weight, and just me and some luggage, (300lbs of luggage), what would you recommend on tire pressure on both vehicles for mostly interstate driving, despite the door stickers, (if recommended)?
