Trailer Tires: High Quality 16's vs. Swapping to 17.5's

Ok so you have 6,005# per tire capacity with a "J" tire where a "H" would have had 4,805#. Now the "J" only allows 62mph but the "H" allows 75mph.

Not sure but the only info I can find on a 40' Mt Rushmore 2006 is it's 38' and has a MAX GVWR of 16K if so that would have at a max weight of 3,200# per tire at 20% pin. Not sure the logic of 6K capacity and the rougher ride it will give and limiting your self to towing at 62mph in some of the Freedom States. But hey nice to have options.
