Well on my tj I ordered the craiger soft 8 with 4.5 backspacing. That made my tires stick out about 1.5 or maybe even 2 inches from the fenders... throws up rocks sometimes but i did like the way it looked. I thought about looking for some 17 inch rims too... I just don't know. I like the alum rims I have that came stock... and there are choices for 18 inch tires out there... I guess unlike a lot of people out there I am not willing to spend huge sums of money for upgrades.... i like to keep it simple. The jeep performs so well stock, I can't justify big money for stuff I really don't need.
