LT tires on TT

Went to a dog trial in New Mexico with my TT.
1000 miles round trip for a weekend trial. A pretty normal event for us. Yes we did "gasp" exceed 65 MPH quite a bit, and we also "curbed" the tires pretty severely on a protruding rock at our campsite. But our LT tires as usual handled it just fine.

I am constantly amazed at what the internet has produced.
We used to call those with little to no experience but vocal opinions "armchair experts"
That has been replaced with the "Internet expert"
The same people with a larger audience.

It makes it really hard for the newcomers to decide what is their best choice.

I have told my story of my conversion to LT tires many times. I used to be a STRONG ST proponent.
Many failures changed my mind... No I did not post up all of my failures at the time, as I had been such a strong ST advocate; that it was,,, embarrassing. Anyone interested in my previous opinions about STs can search my old posts.

I eventually learned the hard and expensive lesson.
Anyone that wants to learn from my past mistakes is welcome to read my past posts and draw their conclusions. ( Use the advanced search, then, archive over 1 year option, my user name as the author and "ST" as the search word). I made this clickable, starting on page 5. Select page 4, 3 etc to see how my thinking changed over time.

Being "right" in this discussion is not important to me. Sharing my experience to hopefully help those that are willing to listen is.

I can tell you a trailer manufacturer that says LT tires can be used on their trailers (Airstream). Can you name another that currently does that, excluding the G614 as it's designated by its manufacturer as a trailer tire?

UMMMMM... There is NO low pressure test for the ST tire. Only the LT tires have to pass that test.

Wait just a minute! What about the ST's much vaunted weight capacity advantage?
You are now saying that it's not real, because it can't pass a test at that rating.

And what about the low inflation test which the ST doesn't have to do?

I'm confused by your questions/statements as they don't seem to line up with what I said. So allow me to start at a different location and proceed from there:

ST tires DO have more published load carrying capacity than LT tires. Those are commonly called the "Rated Loads". NHTSA uses the term "Max Load", but all those words are referring to the same thing.

ST tires have to pass the tests appropriate for those types of tires and LT tire have to pass test appropiate for those types of tires - and they are different.

- BUT - What I am saying is that IF the tests reference the "rated load" and IF LT tires and ST tires were tested in exactly the same way (except for the difference in rated load), then the ST tire is being subjected to a more severe test.

So let's take a look at the low pressure test you pointed to:

That test is done at 100% of the rated load - and there is a difference in that for comparably sized ST and LT tires. For example:

LT235/85R16 Load Range E = Max Load 3042#
ST235/85R16 Load Range E = Max Load 3640# (+20%)

In other words, the ST tire would be loaded 20% more for the same test conditions.

Please note that this low pressure test follows the endurance test (uses the same tire), so the ST tire would have already experienced much more severe testing conditions BEFORE this test started.

That is what I am pointing out.
