Between the two choices which one will stick out less.

-6mm Offset / 4.75" Backspace

0mm Offset / 5.00" Backspace

 

0. Go with a +18 or 35 if you can.

 

Do you have a 4wd or 2wd? If it's a 2wd and you're going to level the back then go with +18 or +35 as said above, but if it's a 4wd then gor with the 0 or +6 offset. The +6 will stick out more.

 

I have an FX4 4wd. So for the above would the 0 offset/5" backspace be the best choice of the two for sticking out the least?

 

Can't answer the question without knowing the width of the wheels. If the wheel width is the same on both wheels, the one with 5 inches of bs will tuck in more. But like I said, can't tell without knowing the wheel width.

 

They are both 18x9's. Ok now that I know the 5" backspace is the way to go I just need to decide which tire size lol.

Either 305/60/18 or 325/60/18 Nitto TG's.

 

If the 325 fits without rubing I'd go with it. A wider tire will look better, but I'm almost sure it will rub. I have a set of 325/50/22 in my shed and they're 13.5" wide.

 

Several members are running the combo he asked about with no problems.
