They'll look good! Of course I'm not a fan of the wheels that are on there now at all, they look like they should be on an early 90's Ford Ranger :p. And I may be biased. These are legend 5's on my Challenger, although these are 17x9's.

And with a 15x7" and 4.25" of backspace you should be able to run 225/60/15's if you want.
