I guess a ask my question wrong, it was meant to be has any one else used a tire that was 14 ply trad and 12 ply sidewall.
The tire industry doesn't make a G load range tire with actual 14 ply tread and 12 ply sidewall...... since the '70s.
New technology gave us a 14 ply "rated" tires that has mostly two very heavy plies that equals in strength the old 14 plys of years back.
I used them on equipment trailers in that era. With 12 ply sidewalls/14 ply treads boy did they ever run hot when carrying loads at highway speeds.
The new tires are just as strong (maybe stronger) and run much much cooler.
Never heard of a Terminator trailer tire.
Looking at the 402 QBC Salem Villa shows a 10644 lb dry with a 2431 CCC = around 13000 GVWR trailer and maybe 6k axles.
Trailers need tires with maybe 10-15 percent capacity above the axles ratings.
