There is no D rated tire in for 14" tires that I am aware of. But you can go slightly larger with slightly more load rating, 215/75R14.
The hassle of your to date experience would drive me crazy. I would get 4 Maxxis or Carlisle HD and enjoy the next 5 years.
The Kumho 857 is a LT tire for commercial light truck, transporter, van and trailers. Only available in 14", it has an 8ply strength (actually twin steel belted with 2ply poly cords) D load range with Q(99mph)speed rating. In 205/R14 it has a max load of 2271 @ 65psi.
I just had these mounted on my rims. Got em at Belle Tire. Special order. No review on them yet. Will put 5000 miles on them this summer to the South West.
