Rear tire height clearance 69 dart

The 215/75-14 is quite a bit taller than any stock tire at 26.9". Typically, they would be more like 25.5 or 26". But there is a fair amount of room for extra height in the rear, and you can always raise it up for clearance (though I don't care for the jacked-up look).

You might want to closely consider the offset on those 8" wheels, to make sure the tire is centered in the well.
