Let's just set one thing straight... "Stretched tires" are NOT correct fitment... That's a deliberately improper fitment purely for having a wider rim. Personally, I think it looks silly...
If you want proper fitment, go with 18x8.5" up front and 9" out back, or go square with an 8.5"... My wheels are 18x8.5" ET35 all the way around... Fitment looks pretty good, and I'm running a 245/35 tire all the way around, again for a correct fitment.
