They will fit, but should be on an 8" rim to fit properly. The stock rims don't have enough backspacing, so the tire will things like leaf springs, control arms, etc, until you get a rim that is further offset.[addsig]
not unless you are wanting those $100 to $200 wheels,go to summit racing ,they have good deals on wheels, I paid 57.50 for a steel chrome wheel that looks great on jeeps and especially on 33 12.5's,its not a lot when you think about the benefits of a 15x10 wheel that doesn't rub anywhere on your jeep,with th proper lift of course!

I have 32x11.50's on my stock 15x7 Ecco wheel, and it barely fits. There is also a little rubbing on the lower control arm in hard right turns that makes this awful grinding noise. As soon as I can afford it, I'm going to buy some black spoke wheels like the American Racing AR767s in a 15x8.[addsig]
