Hopefully someone can help me here. I would like to know if a Nitto 325 60 20 tire will fit on my stock '04 FX4 with a 2.5 leveling kit. I will be using a hot wheels d-back for the wheel. I am not sure of the backspacing, but maybe someone can help me out with that. Thanks in advance.

 

That might be a little big. I have seen 315/60/20 which are basically 34.88

 

Right, a 325/60-20 is basically a 35x13.50 tire. Of course, you may be able to squeeze them on there with the perfect wheel width and packspacing. I think a 305/55-20 (33x12.50) would be a better fit.
