For the last 1800 miles I have run them at 60 psi and have had no problems also the TPMS shows only a 3-5° temp rise over ambient air.
Now do I go by the placard on the trailer or the psi on the tire sidewall?

To fulfil the Carlisle warranty owner obligation, your new tires have to be maintained at 65psi cold, the stated max sidewall psi.
Maxxis is the only ST tire that "suggests" with their load inflation table that their tires can be run at lower than max stated sidewall pressure. I have received verbal confirmation from the Maxxis Canadian distribution center, but nothing in writing.
