Duster 1973 with 15X8 inch wheels front and rear

Nope. 15x8’s in the front would need about 5” of backspacing to run a worthwhile tire. 215’s would be stretched on 8” wide rims, and with the amount of backspace those 15x8’s likely have still wouldn’t fit anyway.

15x7’s with 4.25” of backspacing is what you want.
