wide rubber is the only way to live. as for diameter, same as stock.
Speaking of... I threw my old rears on the front of the car just for comparison. They are running 325/30r20 (27.7 diameter) so no hopes of it answering any problems about the fender rub. However, I am also trying to figure out this offset issue. the wheel is a 19x11 +15et, which means it runs 22mm inboard of my strasse wheel. Outer edge of the tire sits flush with the fender. At this point I am thinking the right offset for the front is going to be somewhere in that +0 offset range.
Sucks to be doing all this measuring after ordering the wheels. Lesson learned, don't trust the stance crowd...
