So the big questions that remain for me are: does a commercial style tire have the proper design to withstand the loading unique to a trailer application? If so, is a commercial tire (seemingly from a more reputable vendor than the ST-style options listed above) superior to the ST alternatives? And finally, who the heck sells a 14" alloy trailer wheel which is rated to withstand cold pressures of 65PSI??
Thank you to everyone who has already offered help.

At the top of the tire chain is a commercial grade or commercial use tire that stands up to all types of trailer use (not just RVs).
There is nothing unique about a ST tire internal construction as far as with standing side loads.
A ST tire and a LT tire and a all position tire all have the same FMVSS 571 tire bead unseating test. Nothing special about the ST being some how superior to a LT or a all position tire.......other than ST tire advertising.
Good read on the subject http://www.rv.net/forum/index.cfm/fuseaction/thread/tid/23225970.cfm.
For a 14" wheel rated at 65 psi check out this add;

At one time HiSpec advertised a max pressure rating which was tied to the valve stem. Give HiSpec a 1-800.
