Goodyear Endurance Tires VS Carlisle Trail HD Tires

IOW, It is illegal to use a ST tire on a motor vehicle.... And perfectly legal to use an LT tire on a trailer.

Its surprising all this has been cleared up many years ago.
Granted lots of new folks pulling all types of trailers (rv and non rv) and the only thing they know about the issue being discussed is what they pick and choose from input from non tire experts on the internet....and ignore input from actual tire engineers.
