Does anyone know the wheel size and offset for the stock Rubicon rims? I want to see what the biggest tire is that I can put on without going to new rims. Also want to make sure tire don't rub.
Thanks

 

I believe its 33's no rub. Someone correct me if im wrong

 

Stuck right to the top of this modified area is a thread with " FAQ's" in the title. You should find rim width and backspace info there.

 

I wheel with a guy who has 37s on his 2011 5 spoke rubi wheels

 

stock backspacing is 6.25" you can run 285/75-17 i.e. 34's if you remove your plastic air dam. very slight rubbing on front sway bar and close to rear driver side lower control arm. it is 7.5" wide and most tire manufacturers will spec what size rim their tires will go on.

 

should I use 1.5" wheel spacers? I also have a 2.5" Rubicon Express suspension lift

 

Are the tires rubbing on something inside the wheel wells? If they are, and you want to move them out to prevent the rubbing, then yes...
