I have done some more research and am still bothered by the max load of 3042 lbs of load range E truck tires compared to load range E trailer tires having a significantly higher max load.
The experience on this board seems to say that truck tires are the way to go, but they are just so close on the ratings!!!!
Many here and forum across the web just do not buy into the inflated ratings of ST tires that are based on speed the restriction of 65 MPH and lower testing standards. ST tires are not low price based on millions and millions of them being built. They are low priced because they are built that way despite the claims of special chemicals and compounds!
A little logic questions how a 35 pound ST235/80R16E can carry more weight than a 57 pound steel ply carcass tire rated to 3042 pounds. LT tires follow long standing industry wide weight ratings that are the same for all manufacturers for a given size. That is a Firestone, Bridgestone, BFG, Michilen, Toyo etc etc in size LT235/85R16E will have the same 3042 pound weight rating. Poly carcass or stronger steel ply carcass makes no difference in what is stamped into the sidewall, they will all be rated to 3042 pounds.
We do not almost daily read about LT tires failing on trailers, and I know many run the XPS Rib and R250 at the max. I personally would not do that with a poly carcass LT unless it was the over built Duravis R500HD with two ply poly sidewall that I just put on my TV.
