An excellent choice, fifteens are old school.

The 17s will allow you to really fill the fenderwells since they'll clear the front ball joints. You can go as wide as a 9 and 10 inch wheel with 255s and 295s, but that's pushing the outer extreme of the envelope and will require perfect backspacing, rolling the outer lips, and banging around on the inner fenderwell in the rear.

A more sensible choice may be an 8 and 9.5 wheel with 245/45/17 and 275/40/17 tires. My personal favorite is this size front but with a 285/40/18 in the rear to give the car some rake.
