Some say, including myself that an LT tire is built to withstand those steering side forces by having a tougher sidewall. On a single axle trailer, there are negligible turning/scuffing forces. As you add axles, the ST has an advantage on scuffing. But that is only a slight advantage given the higher % of time the trailer is on the road.

We were talking about a tri-axle RV not a single axle trailer. I have seen people turn tandem axle trailers with LT tires on them and they look like the tire is going to roll off the wheel.
Ok looking at Goodyear tires, one being the ST Endurance and the other being the Wrangler SR-A both in 235/85/R16,
ST
45lbs
125 load rating
8 tread
LT
44lbs
120 load rating
14 tread
The ST is heavier even though the LT has nearly double of tread depth, the tires are the same diameter and more load range on the ST tire.
So maybe the LT has to pass more stuff in order to carry passengers, has less load carrying capacity and from what I've read, has stiffer sidewalls to help compensate for side dragging of the tire when turning with trailers. Tires rolling through a turn as steer tires do vs tires being drug sideways as a multiple axle trailer is capable of
don't compare.
Ultimately, you can run whatever you want to run on your RV and I'll run whatever I want but from what I've read LT tires don't compare to ST tires in my opinion on a heavy multiple axle trailer. Commercial tires being different, not going there.
