First, to answer the questions about the Tires. I went from MICHELIN LTX M/S2's to MICHELIN DEFENDER LTX M/S, because I liked my originals ALOT. Running around town I keep them at about 45 to 50 psi all around, depending on the heat of the day. Towing I set the front to 64 and the rears to about 74 psi.
For you guys with E rated tires, what do you run non-towing and towing? I dont want to under-inflate them while running around, nor do I want to needlessly over inflate them while towing.
Our trailer loaded for an extended weekend is right abound 6800lbs, and I don't carry water in the tanks. I have no idea what it is coming home, but i do know it feels lighter because we are running with no food, though it couldn't be that much lighter.
I appreciate the feedback and advice, and will take it out this weekend to get the measurements again, and start over. It's also interesting about the mileage to break in the tires, but I've had them for almost five thousand miles (~500 miles towing).
