I think I will keep the LT tires on the tt and I recently ordered a the same kind set for my truck.
I got this from a thread by Lou Amadio Herk 7769 in this forum,
Thanks Lou, Very informative.
ST tires have a unique tread design. There are only ribs and channels that follow the rotation of the tire. There are no (or few) side to side grooves and the tread itself is very "non-aggressive" to provide a minimum rolling friction for better tire life and fuel economy.
In the past, the higher tire loading in high end campers was not being served by the tire industry so to provide the load carrying capacity required they put LT tires on at the factory. Today, there are more choices available and for a given load factor better performance will come from an ST tire.
Under similar driving conditions, the ST tire will provide better gas mileage and longer tire life. During sharp turns the ST tire will crab sideways much more easily than an LT tire. This will reduce uneven wear and "scrubbing" of the tread.
ST tires also have a much higher emulsion content in the rubber since most ST tires don't get a lot of use. LT tires are run at highways speeds more often and the emulsion can lubricate the rubber more easily when the tires get hot at highway speeds. The higher content in the ST tire rubber prevents/delays dry rot in tires that don't get much use.

SO for me that means less rolling friction and better gas milage and if the tires are properly maintained I should have no problems. I have always used ST Tires when available on all trailers I have owned in almost 50 years of RVing. This is the first time I had troubles. I will keep the forum posted as to how well the ST tires do that I bought. I am also buying a TPMS.
