Note to the original poster: everybody is beating around the bush here. Let's cut to the chase: junk the crummy ST tires, and do not replace them with yet more junk ST tires. Buy LT tires, and then go drive at normal highway speeds, and not worry.
Lets make it simple:
ST= junk
LT = good
EDIT: if those are the typical 205/75-14, then what I did was went to a 185-14 Kumho 857. This a commercial LT tire, in a load range D, that is marketed for trailer use also. Tire rack sells them. They work well.
I had to laugh at your EDIT comment:E I see no problems with ST tires and let me share my "experieces" re you specific reference to the Kumho 185-14 tire. From 1995 until 2013 I ran exclusively GY Marathon radials in size 205R75x14 on two different trailers with them loaded to within about 100bs of their max carrying load for well in excess of 75K miles total. I consistently had 6800 to 6900 lbs on the two axles of these two trailers. That's over 18 years of exclusive use. During that time I NEVER HAD A TREAD SEPARATE and only had one "flat" which I discovered at a CG just before leaving. In 2013 I decided to go to Aluminum rims and also switched over to the Load range "D" Kumho 185R14 tires. Last year with just over 4K miles I had one of the Kumhos experience a tread separation:E My spare was one of my old GY Marathons so I put that on and at my first opportunity during our road trip at the time bought another GY Marathon from a WM along our route and that night replaced the remaining Kumho on that side of the trailer with the New GY Marathon. When I got home I bought a 5th Aluminum rim and another GY Marathon and am now running two GY Marathons on one side and two Kumhos on the other side. Evidently either Kumho quite making or don't have available here the 1895R14 tires anymore since no one sells them that I could find.
Just because I had the only "TIRE TREAD" failure on basically a new tire which was an "LT" and not one of the often called junk "ST" tire bombs in a span of some 18 years I'm not going to blame this on it being an LT tire.
At my next tire change out my plans are to give the Kumhos one more chance and in fact will go up one size to the 205R14 tire since those will just fit and I will keep two GY Marathon spares so I I ever have a flat on the road or ruin a tire I can at least replace both tires on that side with the same sized tires.
