Im looking to buy 18's, and was wondering what is the best size and type, to fit a little taller than stock. I have 17's. I want the wheel well to be filled up a little more. mine is also lowered.

Go to www.tirerack.com. They have very informative tire specs, giving overall diameter, load rating, etc. for each individual tire. Useful, as you can check your stock tire diameter, then try a different size to see the difference. :thumb:
