So.. are YOU a tire ENGINEER?
I you take a real close look at ST tire treads you will find less than 1/4 the tread on it compared to a LT tire. This in it's self can account for a considerable amount of weight difference.
Third, ST tires are NOT designed for TRACTION, infact the rubber compounds ARE designed to LOSE traction . This is extremely important when using on two or more axle trailers. The tires on a multiaxle trailer MUST be able to "hop" when making turns. Otherwise you will heavily stress your axles, bearings, springs, hangers and yes the frame of the trailer. Your axles can shift side to side up to two inches while making turns.
This leads to the FOURTH POINT, ST tires DO have extra strength designed into the sidewalls, they have to in order to withstand the side to side stresses of multiaxles.
While there are folks putting LTs on trailers it doesn't mean that it really is the right or correct thing to do in fact some tire manufacturers DO NOT RECOMMEND LT tire usage on trailers. Doing so you might find yourself without any warranty or recourse..
Not a tire engineer but I stayed at a Motel 6 once.......
My 2 axle 5th wheel came with LT tires (all four positions and spare)OEM Goodyears and they are warranted for use on my 5th wheel
