you know - a lot of people go out of their way to get the look you already have... I also have to say this and I know I am probably get blasted for it - those Outlaw II wheels are so truck style..
Anyway - you gotta decide on the look you want and what you'll be mostly doing with the car before deciding on wheels and tires - either the drag race look - typically "bigs-n-littles" - wider wheels and tires in the back with skinnier ones up front. Or the street carver look - typically close to "same same" - wheels and tires are essentially the same size front and back with a slightly bigger tire on the back being a nice variation to this... (essentially what you have going already) of course you can vary these "formulas" but they really are the two basic starting points... again though, what's wrong with the current set up? I like the semi-same same tire on Mopar rallye wheels look...
