Does this also apply to running them on a unloaded vehicle too? I was running them at 35 unloaded and that is what I was running the other rated ones at.
I do not know for your tire what the minimum inflation pressure is. You should consider calling the manufacture and asking for customer service. You have a LR E tire made for 80psi, running it at 35psi is more than 50% of the max pressure. That may or may not create issues. There is for sure a load part of this, but the tire may have other issues being that far down the pressure range.
I tried to find a tire pressure chart on your tire and I cannot find one.
Goodyear has one for Goodyear tires.
http://www.goodyearrvtires.com/pdfs/rv_inflation.pdf If you scroll down to the LT's, you will see a load verse pressure for the size. They do stop at 35psi for their tires. This seems to point to a minimum for a tire rated that heavy.
You for sure have to have enough pressure for the load, just there may be other concerns on that type of tire going down in pressure regardless of load.
I would check this out before you run that low very long. 35 psi on a 80 psi tire is not much. I have never run one that low. It may be OK or not.
Hope this helps
