Please help.... failed inspection!!

Hi guys,

I installed Nitto Terra Grappler 265/70/17's with 1.5" wheel spacers last summer on my 2006 WK Limited. I obviously needed to get the wheel spacers. Problem is, I brought the Jeep in for inspection and it fails here in PA if the spacer is more than 1/4". I don't have the stock tires to put back on nor a set of spare wheels. It pretty much comes down to buying a new set of wheels. I need to know what the factory backspacing etc... is for the stock Ronin II 17" so I can get an aftermarket wheel with the correct backspacing/offset. Please advise!

Thanks,

Rob

easiest way to check what you need is to take off one of your front tires and the spacer, then put the spacer on the rim like it sits when mounted, then measure from the face of the spacer to the back edge of the rim and that will be your current backspacing you are using. if the spacers work fine then find a rim with the same backspacing you are using.

See if you can find a local forum member who's willing to swap wheels for inspection. If you were local I would certainly do it for lunch and a beer. :-)

Alot cheaper then new wheels.

The factory backspacing is 6.25" and I have an 1.5" spacer, so I guess its 4.75". Now the factory wheel is 7.5" wide, if I find a wheel that is 8" wide with 4.75" backspacing where will that 1/2" difference be? By the way, thank you very much for the quick help!!!

If the backspacing is the same but the wheel is .5" wider then it will stick out. 5" more.

How important is the bore of the wheel? I found a set that has a 78mm bore and the factory wheel is 71mm..... Is that okay or does it need to be exact?

Better to be hub centric if possible, I believe you can get rings to make it fit the hub better. If it's not hub centric, the stress of the wheels and vehicle weight rides on the wheel studs.

The irony is that a 1/4" spacer is acceptable, yet more dangerous than a bolt on spacer. Go figure...

I agree.... I for the life of me can't find anything hubcentric within my price range... Any suggestions?

Ideal fitment for a 17 inch after market wheel would be a 17 x 8.5 with an offset between +10mm and +18 mm. That will give you appropriate clearance from steering and suspension components without pushing the tires too far outside of the fenders. Many companies make hub-centric rings that will take the center bore of the wheel down to the hub size of the vehicle. They make both plastic and metal rings. I would use plastic rings because I have seen (especially in areas that have a lot of snow with salt of mag chloride on the roads) I have seen metal rings get corroded on to the hub and are a real pain to get off. Both plastic and metal function the same, but if the plastic rings get stuck they are easier to remove. On average a set of plastic hub rings run $5-$10. So if you need to buy new wheels, find something you like the look of, make sure it is around 8.5 in wide and in the correct offset range, then finding hub-centric rings should be easy and inexpensive.

Thank you very much! I ordered a set of wheels 17x8 with a 4.89" backspace and a +10mm offset. The hun bore is 78.1mm. The stock hub bore is 71.5mm.

It looks like it fits into your suggestions correct? Where can I find the right bore spacers?

That's great. I'm glad you were able to resolve this. I'm really glad we don't have ridiculous laws like this in N.C.
