I know backspace issues have been beat to death, but I could not find a thread that specifically answeres this.

I know my leveled 05 Screw 4x4 has 18x7.5 OEM wheels have 5.5" backspacing, I'm going to a 17x9 with 35" BFG's, the two wheels that I am looking at have either a 5.5" backspace or a 6", which is going to cause me the least amount of rubbing issues or are they equally compatable ?

Thanks for your time.

 

I think you should stay with the 5.5" backspace if you plan on getting beefier tires. If you go with a 6" you may have to trim more plastic or get possible rubbing issues. BUT, the 6" backspace could give you a better look with a wider wheel since the wheel/tire should not stick out by much. Ask them to try a wheel out BEFORE they mount it just to see if you like how it looks. They should not have a problem in doing this and may save you from a costly mistake. Good luck

 

the more backspacing the farther the wheel will be in the fender well. less backspacing will make it stick out more.
How to measure backspacing

 

Yep, I had 4.25" on some wheels I purchased for a lift and they stuck out about 3 1/2 inches. Never got the lift and sold the wheels. Lost a few hundred dollars.

 

Both will work. It just depends if you want the wheels to stick out 1 1/2 or 1 inch farther than stock.

 

So the 5.5 inch backspace rim will stick out 1.5 inch further stock and more than the 6" rim just due to the new widder rim width ?

 

Right. Since they both have the same backspacing, but one is 1 1/2 inches wider, it will stick out 1 1/2 inches farther.

 

So if I have an 8" wheel with 4.5" backspacing it should put me 1.5" out?

 

Right.
