I have read the government test standards for ST and LT. Yes, the LTs undergo far more rigorous tests that STs. That is because LTs are designed for trucks and the stresses associated with truck service. ST tires are tested for the stresses associated with trailer service.
If you wish to believe the more rigorous LT testing makes them suitable for trailer service and the LT manufacturers are stupid for not recommending they be used for trailer service, go right ahead.
I would add that Indy racing tires also undergo severe stress and testing, so why don't we all switch to them?
My thoughts and feelings as well...
For sure not mine.
I've read the FMVSS testing requirements and there are no different test associated with trailer service. So if you have some different info on tire testing than the FMVSS please shows us what and where we can view that type testing.
This we know.....
The ST is to be used in a trailer position only.
The LT can and has always been use in a steer/drive and trailer position for many many years before the ST tire was ever placed in service.
Now your comment about Indy tire;
Indy type tires have a very high speed rating and little to non load carrying ability so they make a really silly example for using in a trailer position. If you have a link to their testing that you think makes them a candidate for trailer service show us that also.
