Yes the rims will fit, it's the tires you need to be careful of. I agree with don703 above. If you have money to spend, make sure you're not letting more important items go If you want, go for it. You may have to shave the rain channels off the fenders or tub the rear to make the tires fit. rim shops and tire shops deal with this all the time. The honest ones will tell you what to get, not sell you something and laugh.
