Thanks for posing this question as I had been looking all over for the answer to this question this past summer and couldn’t find a definitive answer.
I have a pretty much stock 2011 F350 6.4L dually and a new NL 10.2. The only suspension enhancement I’ve put on my truck is Torklift’s lower stable loads. I also put new Michelin tires on the truck a couple months ago, same size as the stock BF Goodrich that came with the truck purchased new.
I thought my truck rode just fine without the camper on it, but it felt a bit soft and out of control when I had the tire psi at 75psi front and 60psi rear that Ford recommends for my truck.
I checked all over Michelin’s website for recommended psi’s for my tire size, and the only charts I could find were for RVs and heavy duty trucks., that were all larger tire sizes than I have. However, regardless of tire sizes, Michelin’s charts always recommended higher tire pressures for heavier loads.
With that in mind, I checked with my local tire dealer, which Michelin recommends on their website, and my dealer said he thought he would run something like 70 psi in the rear with the NL on it.
In any event, with all of my wisdom (ha, ha!) I decided to run at 75psi all around, so that’s what I did. It seems like my truck certainly drives and handles much better with the tires inflated to that level, so that’s what I’m going to keep them at for now.
As an aside, I had troubleo with Michelin tires in the past on my 2000 F250. According to a service tech at a Ford dealer I went to, Michelin has softer sidewalls than do some other tire manufacturers, and that, coupled with a narrower rim that Ford was putting on their trucks at the time, compared to Chevy and Dodge, resulted in the tires sitting flatter on the ground. Anyway, at the time I switched to Bridgestone Revo tires and that solved the problem, so I assume the dealer was correct in what he said. In any event, I think I was having too soft of a ride, versus too hard of a ride as you are experiencing.
