LT tires on TT

There was a recent topic started by Partymarty that compared Goodyear tires sized 235/85R16E . One was an ST and one was an LT .

The ST standard rated the ST tire for 3640 # and the LT tire for 3042 # .
The ST tire sold for 80 % of the LT price .
The ST tire weighed about 80% of the LT tire .
The ST tire is placarded " for trailer use only " .
No disclaimer for the LT tire .
The ST tire is based on a 65 mph max , and the LT is 99 mph .
The maker was Goodyear in each case .

A logical conclusion is that the ST standard is a weaker standard .

:h
I can't find any Goodyear ST tire in that size-? Apples to oranges otherwise...

That said:

Of the above, the ONLY reason that in my mind necessitates a switch to LT's is the speed factor. For folks that intend to drive at speeds above 65 for extended periods of time, a higher speed-rated tire is the best/safest alternative.

But for those who tow at more moderate speeds the following might be considered:

- Unless the two tires in the above post are indeed exactly the same dimensionally, weight certainly can't be used for comparison.

- Since (any) tires mounted on a trailer can be expected to have a reduced life span, lower per tire cost should work in favor of the ST.

- The ST obviously will carry more load than an LT of the same size, which should be another strike in its favor.

- On the other hand as noted above, that extra capacity comes at the expense of speed, reduced for the higher load-carrying tire to 65 mph. (Interesting side note: Same reduce speed/increase load rule governs LT's- reducing speed for increasing load is SOP per many mfr.s advice including Goodyear. Link)

-ST tread design is inappropriate for drive/steer axles, which accounts for the so-called "limitation" to trailer use. Many jurisdictions allow folks to ride in fivers/trailers without tire-type limitations, which explodes the popular myth that ST's are somehow "not safe for passenger carrying".
