I don’t know if it will fit but IMO it’s too big anyway. That’s over 27 inches. I am running a 205 65 15 which is about 25.5″, about the diameter of the original 15″ option. The 13″ rims ran even smaller tires. The side wall on a 205 75 is going to be very high and it will roll a lot resulting in poor handling. More like a small truck tire. Of course the large diam also effects your gearing. Check out a calculator on line and you will see how it changes your gearing. Your backspacing is okay I think but might be moving the wheel in a little too much. Lots of info on tires and wheels in the forum. Use the search all the way at the bottom of the page to do some searches.
