Are you ever going to want to use chains or cables? I think you are not planning to drive over the mountains in winter, so I guess not. Thus you could use the wider tire if you want.
Use a tire calculator to see the effects.
Youre right about the size being close, BUT 245-50-17 is a really rare tire. there are only a few tires in this size. My folks had to buy TWO sets for their Acura RL, and found out the hard way.
At ANY price, you'll be surprised how much you like these...

The Yokohama TRZ, and H4-S are both excellent tires at a good price. In that size, the sky is the limit.
Also, Wider tires would look nice, BUT, I've always found that on a given rim, a wider tire may provide more grip at the limit, but wont be as crisp on turn-in as the OEM width.
A wider tire has more room to distort under load unless the rim width increases.
