Coker Tire has some oddball stuff that is tall and skinny. 4" wide rim is a tough one. A 5" or 6' rim would be way easier.
More on there than this one that I picked as an example. Pie crust sidewall might not be ideal for a newer Dakota.

For that kinda money I'd buy something more upscale like something from this place.
