I was wondering if I could run a set of 33X12.50X15's on my 2004 FX4 with a 2.5" leveling kit if I use a set of Pro Comp Extreme Alloys Series 1079? What backspacing would I need to be sable to do this?

Thanks!!!!

15's? The bits I have read on here, you might have problems fitting 15s over the brakes. You might try searching a bit more on the subject if you need an answer right away.

I'm sure someone with more knowledge on here, can confirm in a little bit.

 

No, 15's won't even come close to fitting. You have to use a 17 inch or larger wheel. However, with a 2 or 2.5 inch leveling kit you can fit a 33 inch tire on a 9 inch wide wheel. I'd recommend one with 5.5 or 6 inches of backspacing. In my opinion, the best looking combo is a set of 325/60-18 tires (33x13.00) on an 18x9 inch wheel.

 

Here are some pics of the PC 1089's. 17x8 with 4.5 inches of backspacing and 0 offset. The are some pics in my gallery that show how much tire will stick out.
