Re: What tires to buy??
Stay at 32" diameter or smaller and be sure you also change your spare to the same diameter as the other four. And note that your speedo and odo will no longer be accurate if you change tire sizes from OEM. Dealer can't fix that, either. (reportedly a Diablo tuner can, but that's a big chunk of change)
The major online tire retailers have calculators on their websites that will help you answer your tire size possibilities and then suggest those available for your 17" wheels.
