$86/wheel! Holy s**t that's a good deal. You're in Canada like me though so it'll be more like $100/wheel plus shipping. Try to get the company to label the box as product testing as well so you don't get hit with as many border fees if the border decides to check the package out and tax it. Sometimes they won't tax at all, and sometimes it's ridiculous.
The 615's only come in a 205/50/15 and on a 15x8 it won't be stretched at all. My 195's barely look stretched. If you want a super stretched tire you're going to have to find some rare sizes, anything from 175-185/50/15's will give a decent stretched look. The Azenis will give amazing grip, but will look pretty big on that wheel. Good thing you're going with +15 offset because to clear those wheels with a 0 offset you'd need to add camber in the rear.
Are you front or rear fenders rolled/flared at all? It'll be interesting to see how low you can get up front without flaring the fenders. I originally flared mine and they fit the 15x8 0 offset fine and I'm slammed, but I never test fit them before the flared fenders. Personally I'd go with a 195 series tire, it'll be a tiny bit stretched, but it will also help out with a lot of rubbing issues you'd have with the 205 series. The 205 Azenis is a very good tire though and will grip way better then most any 195 you'll get. Width=grip basically and the product obviously.
Most important part with fitting these wheels here though is if you have rolled/flared fenders. Let me know on that one....
