What size tires are you guys running on the stock 18" wheels? Mine had 245/55/18 goodyears when I got it and those, and 1 other tire are all I can find in that size. I was thinking of stepping up to a higher width maybe to open up more options?

245/55 15 is factory size. You do have options as far as tires go

Tirerack and discount tire direct are your best option

New 20" wheels... :whistle:

None on DiscountTire. Tire rack has a few but if you jump up to a 255 there are over double that. That's why I was wondering if anyone has gone bigger. I'm sure the speedo might get off a little but it opens up a lot more options.

245/50 opens up A TON of options. Thanks, that makes a lot more sense. Not sure why the previous owner went 245/55???

There's a good calculator for wheels and tires you can use. Check the wheel fitment guide in the sticky threads.
