Any tire with a diameter more than a 650X16 will cause interference with the fender indent. a 650 is about 29" in diameter a 215/85 is over 1-1/4" bigger in diameter and probably an 1-1/2 wider too which exacerbates the fit even more. You could carry a smaller spare, it wouldn't upset the looks too bad either.
