Thanks the bumper is a rugged ridge XHD with hoop, Purejeep shackle mounts and a custom welded light tab all Line-Xed.

Call the lift company and ask them want they recommend for BS for their lift. You can always add spacers, but why spend more money. Just get the right BS the first time.

 

9" Wide Rim:

-12 offset = 4.52" back spacing
+18 offset= 5.70" back spacing
+35 offset= 6.37" back spacing
All Jeep JK Factory alloys= 6.25" back spacing

-12 offset rim and any 35x12.50 tire will work.

 

What about a wheel like the XD Misfit that has a Zero offset???

 

9" Wide Rim:

0 offset = 5.00" back spacing

Here's the calculator I use: http://autolounge.net/calculators/tirespacing.html

 

Got ya. Think I get it now. So since I want to keep it at 4.5 and I'm at 5.0, would I add spacers?

 

Bump fellas.

 

Then I think you'll need some spidertrax spacers, 1.25 in or 1.5 - whatever ur preference. I have the same question tho I want XD Rockstars 18x9 with 35's and I don't really want to use spacers but I don't think xd's come with any offset for the 18x9 size?!

 

By my understanding:
Backspacing is the distance from the hub-mounting surface of the wheel to the inside edge of the wheel.
Offset is a measurement of the hub-mounting surface relative to the center of the wheel.

therefore:
Backspacing on a 9" rim with 0 offset is 4.5"
