I have a 2004 fx4 with 2.5" leveling kit. I want to get 17" xd addics with 35" nitto trail grapplers. I need to know what the bolt pattern is and what offset I should buy. Thanks for the help.

 

Our bolt pattern is 6x135. I'm pretty sure that our stock backspacing is 5.5". Not sure on the offset. Hopefully someone else will chime in on that!

 

+18 offset will fit with very minor trimming

 

Offset on the factory wheels is +52 most people want to bring the rims out at least even with the side of the truck which would be ~ +20. I personally wanted a bit more aggressive look and went with a +1 offset and my rims and tires stick out about 1"-1.5". I have 305/55/20's (33.2" x 12") and did have to trim a little bit due to the offset width combo but 275/60/20's (33" x 10.8") did fit with out trimming.
