The ST205/75R14 tire already gives me a 42% cushion. 1760#x4= 7040#. My TT's GVWR is 4950#. I'm guessing that's enough.
I do not want to spend money on new rims. My current aluminum rims are rated to 60psi. If my rims were rated to 65psi, I'd probably put the Kumho's on them. That would be an easy upgrade.

instead of replacing all of the tires i spent the extra money ( saved by not buying a new spare ) to upgrade the load carrying tires an extra size and an extra load rating .
i picked up an extra 35 % in load rating capacity in pounds as stated on the tire sidewall . minimal cost while replacing .
i did this because i occasionally tow long distances starting at 5 pm and towing through the night . i do not want to change a tire in the dark .
i sometimes do this both directions to really far destinations .
i probably pick up an extra mpg or so due to no traffic and i certainly can average a couple of mph better also even at the same cruise setting .
we don't have a freeway in central oregon and it is mostly 2 lane US highways such as hiway 97 , 20 , 26 , and so forth .
