If your looking at downsizing the factory rims and upsizing the tires, then your in the right place for info, if you're after 22 chrome wheels
, then you won't find this site to your liking.
Is it worth it to buy an '04 overland? sure, how much are you paying for it?.
As a general rule, the last run of any model tends to be the most reliable (it's a jeep though), and most of the issues have been "resolved", in fact technically, if it's a late built '04, even the blend doors should be "improved" from the factory.
If you want to wheel in style, that is the ultimate ride, put a 4" lift and some mudders, and youre good to go.....quadradrive standard.
