Been studying this thread the past few days! I'm glad the 300s worked, going to look for some also. BTW, the p/n for a 17x7 version of the 18 hole wheel mentioned a few pages ago is 52125069AA. that's my full size spare.
Thanks! Do you know the BS on the full size? I know the stock 17" for KJs are 7.5 inches wide, and some KKs have 17x7 but I I thought all of those (aluminum wheels) had 5.5" of BS. I would assume the steel would be the same....
From my experience, the wider the wheel/tire package (i.e. from a combonation of wheel width, tire width, and Back Spacing) the more it will cause rubbing issues. However, you need enough back spacing to keep the wheels off the sway bar.
The 255/75r17 tires are a nominal size of 32.1" in Diameter at 10" wide. They fit on the JK wheels that are about 6.25" BS but I have 1.25" spacers so that puts them at 5" of BS. I believe with taller than 31" tires, you would need to run more than 5.5" of BS to clear the sway bar, generally speaking. Now, since I have narrowed my wheels from 7.5" wide JK wheels to 7" wide Chrysler wheels, but added about .5" of BS I am sure I will clear my sway bar but I hope I do not rub on the pinch weld.
There is a lot of research and math involved when changing wheels and tires from factory specs, so I just hope I got it right and I do not waste money
