Found a cool tire calculator website. Great way of figuring out overal diameter. https://www.1010tires.com/tiresizecalculator.asp Here is what I have deduced!
215/60/16 stock
215/65/16 adds .85'
205/70/16 adds 1.14'
215/70/16 adds 1.7"
I have found on this site in various places by various people that these fit on a stock 1st gen Forester. I have my doubts about the big uns.
If you took the middle size plus the 1" blocks from subtle I would have over 2" added ground clearnace. I'd be pretty stoked with that.
You have calculated the increase in tyre diameter. You will only get half of that increase in ground clearance - 0.42", 0.57" and 0.85" respectively - since it's the change in radius that will determine how much you're lifting the hub.
