I'm trying to find out which tires besides the stock 205-70-15's, will fit and be able to be used on my factory stock 96'outback legacy. I have some 215-65-15's. will they be alright to use???

As long as the circumference of the tires is within a quarter inch between all four you will be fine.

Probably will fit. I have 215 X 70 X 15 size on my 99 OBW, which is the same car that you have. I have no rubbing issues. Car sits a little taller. Just be sure to use the same size tires at all four corners. Subaru AWD requires this.

punch in the stock size and the size you are thinking about using and it will show you the differences.

you can switch between side and end (tread) views, and it will also tell you how far off your speedo may be and which way (slow or fast)
