dont make the mistake i made, you dont want 15" rims...
205/60/15 just like stock, well wider than stock, but same height
205/45/17
also mine is lowered 2"f/2.5"r so if your still stock height, it will look even worse with 15's...
^^^^Agree 100%
Might be cheaper to buy 15" and use your existing tires but not going to be any easier.
If you are going to spend the coin for nice rims why not go with 17" or 18" and low profile tires. Use the tire calculator to get a size that is the same overall diameter as your 15" - any tire shop shop should be able to help you here as well
Better looks, better handling - no reason to stick with 15" unless money is real tight.
Don't forget to keep the stockers for winter use
I think 18's would be good. I have 17's with 205/40/17's on mine, without being lowered it dont look so good.
