With the new 3.6L and 4.10s, you'll have no problem spinning 35's. I have a JKU and 3.73's with an auto. After updating the ECU with a Procal, it drive's almost like stock with 35's.

Only if you have a lift or upgraded steering that requires additional backspacing. Or if you like the wide-stance look. My DC2s have 4.5" backspacing which is plenty, but I had wheel spacers for my stock wheels on 32"s after my lift kit.
