LT vs ST tires

Really good information.  Thanks.  I noticed that at our Northern California pod feast, most of the campers had ST tires.  Mostly Goodyear Endurance.  Some of the newer R-pods still have the LT tires.

My speculation is that they used LT tires with aggressive mud/snow tread for marketing reasons; to make the trailer look like you could take it anywhere.  The problem with LT tires is that they have more flexible side walls than ST tires, allowing more trailer sway.  The reason for more flexible side walls it to provide a more comfortable ride in a passenger vehicle and more cornering stability.  That flexion is not helpful with a trailer.  There really isn't any off road advantage to the LT tires.  Since the trailer isn't pushing the TV in slippery mud or dirt, any additional traction provided by LT tires with aggressive mud/snow tread is not really advantageous.  If you are going so fast that the trailer is sliding in the curves, then the better choice may be to slow down some and allow the trailer to track easily behind the TV.  I suppose in some snow the tires might perform a little better with braking, but once it gets icy, that advantage is minimal compared to the traction gain with chains.
