The awesome thing about the 15s, is that even in a 50 series they can be more than an inch shorter than 35-45 series17s or 18s. Thereby lowering your entire car without affecting your alignment. Which of course is great for lowering your CG without F*n up your camber curves. Problem is 15" rubber maxes out at about 225s unless you're talking about slicks. You're better off stretching a set of RS3s or XSs in a 225/45/15 than you are trying to find some random tire that just happens to be wider and 15".

The whole point of this Maximum TIRE thread is performance. Not just meats for meat sake. And in you're case you'll get better performance by going smaller because that's where the good tire compounds are available.
