Fits perfectly fine, even on the stock rim. I have 245/45/17 General Exclaim UHP's I got from Tirerack on the '06 factory rims. I wanted the extra 20mm of width for the slightly more aggressive look it provides. I had no problem whatsoever with the rim width, despite the "official" position. Nor did my tire installer. My only real concern was that I'd end up with a heavier tire that would hurt acceleration and gas mileage. The listed weight for the Exclaim was near the weight of the factory Michelin, and I have not seen any decrease in either mileage or acceleration, although the 245 is a fraction shorter, which may push the numbers a little. But as far as I am concerned, the car should have come with a 245 in the first place. The bonus was that the Exclaim was way cheaper than the Michelin (or just about every other tire out there), and it has a better grip.
