Recently purchased a 2011 screw fx4. I'm soon going to be adding a 4" rough country suspension lift. I have been debating on rims and tires finally think I decided on the 18x9 xd series addict black machine. That way I can tie in the black step up bars an bumper I hope to add an still have silver paint and machine metal together. Anyways, I'm trying to decide what size tires to run and what offset/backs pacing (ive read but I can't get it). I want minimum wheel well space so figured I would need a farely tall tires, but want minimum to no trimming... Here is where I get really lost currently I have stock fx4 flares but hope to add 1.5" bushwacker flares and want my tires at least as far or a little farther out than flares. I'm not sure which would look best. I'm sure the offset will determine this, but I don't know how to figure it. So I'm here asking the wheel/tires gods lol. Curret rims I found have a -12, +18mm off set no clue what that means...please help trying to see what I'm getting before I spend 2k in tires/wheels and 2k in a lift if it's worth it

 

Anyone?

 

I'd go with a 9 inch wide wheel with 5 inches of backspacing and a 35x12.50-18 or 325/65-18 (35x13.00) tire personally.

 

Thanks

 

Sure you figured it out by now but backspacing is measured in inches from the mounting plate to the rear (inside) lip of the rim. Offset is almost the same thing measured in mm from the centerline of the rim to the mounting plate. If the mounting plate is to front (street side) of the centerline then it's a positive offset, if the mounplate is to the rear (inside) of the centerline then it's a neg offset. Hope this helps.

By the way, did you ever get those rims? Any pics? Cheers.

Also should mention that this means if you have a neg off set this will give you the "deep dish" look but will make your wheels stick out more. If you have a positive offset then this will give you a more flush look and will suck your wheels into the fender. Sounds like the look you're going for will land pretty close to +18mm offset. wouldn't go higher then that since you have the fender flares. also, your stock rims are probably somewhere around +44mm (just so you can have an idea).

Im pretty sure the rough country lift requires 4.5 inches of backspacing so a negative offset will be the way to go
