Wide Rim Offset question...yep another :)

I am getting muddled here with opposing opinions.

I am concerned about wheel to stop clearance in full turn and with tire to frame (etc) clearance in the rear.

Hypothetically what is the least amount of back spacing a person can have on a stock JK if the measured section with is 12.5 inches on a 9" rim?

I dont want the tires to stick out any further than they have to.

My old JK I had PXA7069-7973's 17x9's procomp's with 4.75" back spacing and there was a pretty big gap behind the rear wheel which made them stick out.

I can't remember how large the gap was though in the rear. It seemed to be out about an inch and a half further than it really need to be for street driving without compensating for arch during articulation. Just on a level surface.

Could I person go with a 6" back spacing on a 12.5 on a 9" rim for street driving?

Thanks in advance

Jeff

Your factory wheels have 6.25" back spacing. About the biggest tire you can put on them without a lot of rubbing and no spacers is a 285/70/17 and it is very close to the sway bar links in the rear.

The answer to your question really relies on your tire choice more than anything.

It would depend on how tall of a tire also... especially in the front.

I have read repeatedly that stock 17" wheels are 6" backspacing so the short answer would still probably be "NO"!

With stock 17" wheels, a 1 1/4" spacer, a 35x12.50x17" tire would barely rub. I never felt it but I saw the marks it left on the rear wheel well and the front lower control arms and (I think but not sure) the swaybar also.

This was an 8 1/2" wheel but not sure if it would make much difference?
