I saved a pic & post done by "Lambeau" from a few years ago:

It shows his big/tall tire winter set up; the size he used is very, very close
diameter-wise, to your intended set up. I don't guarantee it, but the specs
are damn close, nominally, though tire brands/sizing can vary considerably
from brand to brand.
Here's an easy link to check up on my arithmetic, which I used to give you
a ballpark:
Tire size calculator
Using the two tire sizes shows that Lambeau's snow tire set-up is actually a
tad bigger in circum than your potential size usage, though brands really have some
differences in real world actual 'dimensions', but you
may be in the right zip code.
