Correct inflation of trailer tires
Everything I read says tires should be inflated to Max psi. Is there general agreement on that? I plan to do whatever is safest and as of last evening, my tires are at 60 and Max is 80, so I have some...

Most def. max. sidewall psi unless you're rims can't handle it. The tires will age out long before wearing out. For plenty of great info. on RV tires by a retired tire engineer, visit RVtiresafety.net.
We just got a new set of Endurance tires installed and have them inflated to 80 psi. What I did notice on the sidewall instead of just "max. 80 psi" is that the tires now say "for max. load capacity inflate to 80 psi. Our old tires were Marathon LRD and I kept them inflated to max. sidewall psi of 65 psi at all times. Got 5-1/2 seasons out of them and well over 20K miles.
What you want is a min. of 15% reserve load capacity to reduce the risk of a tire failure. If you previously had LRD tires at 65 psi and had at least 15% reserve capacity, you could reduce the pressure down to 65 psi and get the same load capacity you used to have.
Only have about 50 miles on the Endurance tires so far and can't really tell if there's much of a difference yet. There def. isn't a harsher ride to me, which some say there will be. FWIW, I have the rear tires on our truck at 80 psi rear and 65 front as per the OEM specs.
