Backspacing and width of Factory 18" FX4 wheels

Does anyone know what the width and backspacing is for the OEM 18" FX4 wheels on the 2006? I am trying to find aftermarket wheels as close to this as possible. Oh and I guess I would need to know the offset as well(?)

Thanks

How would this set up look or work on a 06 FX4 with stock suspension?

ATX ARTILLERY (with BFG All Terrain T/A KO 285/65-18)
Size: 18 x 9
Offset: -12
Backside: 4.53

Would the tire stick out from the fender, if so, by how much? I’m trying to keep the original look of the truck but with a little bigger tire and some new rims.

Thanks

Those wheels will stick out about 2.5 inches farther than your OEM wheels.

Thats about right. If the tires are not super wide (275'ish) they will come right out to the edge of the fender up top and be out down near the rockers. And they will throw stuff up the side of the truck.

A good rule of thumb: 9" and or offset that is negative will usually need at a minimum a 2-2.5" lift up front with conservative tires, and probably a lift if the tires are bigger. This is an ATX Vice in 18 x 8.5, +30mm offset on my truck. Even this comes quite a bit further out.

Dont mean to thread jack here but im looking at getting a set of XD addicts in the 18X9 with the +18 offset and 5.71 backspace. Im going to run a 35 X 12.50 with a 2.5 leveling kit. I have run the 35s with the stock wheels and some rubbing so hopefully this wheel will fix that. Any thoughts?

Sweet Truck Man!
I'm not 100% sure, but i don't think 5.71 is enough backspacing on a 9" rim with out trimming. I may be wrong tho. I just wanted to compliment you on your truck, it's reall nice.
