I think it will mostly depend on how big you go with tires. The American Racing rims I just put on were 16.8 with a 0 offset and 4.5 on the backside and they don't stick out that much at all. At least, imo they look good and the amount of sticking out does not bother me in the least. But, I think it depends on the size of the rim and the manufacturer. Worm's rims seem to protrude a little more than mine, but I think that might be because they are bigger.

Here is the thread about my rims

I also only put on LT245/70 R16s and only had to trim a smidge, which is fine cause I really didn't want to trim at all.

PS - I know exactly what you're going through, I dwelled on those Chambers for like 6 months before I actually worked up the nerve (and the money) to buy them. Its a lot of money for something you aren't 100% positive will work.
