If you are going to run 37s, my wheels I ordered have a 5 inch backspace. I ordered the 1 3/8" adapters to go from 5x5 to 5x5.5 bolt pattern, which reduced my backspacing to 3 5/8". My tires are 37/13.50x17 and they don't rub at a full turn. If I would have not used the adapters, my wheels would have been tucked in too far and would have rubbed on everything.

Backspacing is measured from the back lip of the rim to the flat area where the studs go through.

If you would like to see it, just let me know and we could meet up so you can actually see what we are all talking about. I am in Moyock..

 

I am probably going to stick with the 35's at this point, maybe further down the road I will move on up to the 37's. My reasoning behind this is so that I can put the 35's on now and regear later down the road to 5.13's and then move up to the 37's. If anyone had pictures of a 315/75r16 on the stock X 16's that would be awesome! Thanks for the offer to see your Jeep, I may take you up on it.
