One option for replacing a single tire on a 4WD/AWD vehicle and matching size is to find a tire store that will shave the new tire down to the same tread depth as your existing tires. Although it seems a bit of a waste, you are preserving a lot of miles on the existing three tires.
Racers and autocrossers frequently shave tires to reduce tread depth to make the tread stiffer and less liable to chunk. If you can find a shop that sells tires for competition as well as regular tires, you may be in luck.
Good luck,
