I'd like to see how ST tires would match up if they went thru the much more stringent LT tire spec requirements tests from DOT/UTQG,US Government, etc...

Hate to burst yer bubble, Bub, but LT's aren't subject to UTQG testing/standards like passenger car tires are.

That's why the letters on the tire are so different- pretty much the same codes on an LT that you'll see on an ST.

Should have written NHTSA, not UTQG, as you are correct about UTQG.

That doesn't change the Bottom line though...
Much higher testing requirements on all LT tires rated to carry humans, with reserve capacity, compared to lower requirements for ST tires.

Here is the link for the NHTSA site lots of reading there, check it out yourself.

And its going to get worse real soon. Even less stringent requirements for ST tires, possibly real soon. Thanks to trailer manufactures wanting cheaper trailer type tires...

NHTSA

"On March 13th,2013 the National Highway Traffic Safety Administration (NHTSA) published notice in the Federal Register of its intent to clarify that special trailer (ST) tires are permitted to be installed on new trailers with a gross vehicle weight rating (GVWR) of 10,000 pounds or less and that such trailers are excluded from a tire retention testing requirement of FMVSS 110 that was intended for passenger cars, light trucks and buses.

This issue was brought to NATM’s attention by member companies in 2012 and the NATM has been integrally engaged in working with NHTSA and industry allies to achieve resolution. The coalition, which included the NATM, Recreational Vehicle Industry Association (RVIA) and others, carefully reviewed the regulatory notices that created the requirement for rapid tire deflation testing, and reviewed relevant safety data. After substantial efforts, NATM and the coalition encouraged NHTSA to revise the regulations to clarify that rapid tire deflation testing requirement was not intended to cover trailers and it worked with Transport Canada to minimize the impacts to imports into Canada while the process was underway. The action proposed by NHTSA will now enter a 60 day period for public comment and NATM intends to submit comments supporting the clarification.

NATM was extremely pleased with NHTSA’s responsiveness on the issue, and if NHTSA adopts the proposal, it would remove a potentially significant regulatory impediment for NATM members companies."


By the way,just in case you don't know,
NATM, stands for
National Association of Trailer Manufacturers
