You didn't mention what wheels you're running or their backspace, but with 4.75" backspace, I've run 35" tires without issue.
Here's some more information that may help you.

If you go bigger than 35" there are a lot of other mods you will need to plan for. So that would be my recommendation. Also think about wheel spacers as mentioned already you may have rubbing depending on what back spacing you already have.

32" tires: no rubbing
33" tires: some rubbing can be cured with minor trimming of the stock airdam (applies to 12.5" wide tire)
35" tires: don't try (12.50" wide tire will rub without aftermarket wheels or wheel spacer)
The JK with stock wheels, 1 1/2" wheel spacer, no lift, Bushwacker flat-top flares
32" tires: no rubbing
33" tires: no rubbing
35" tires: rubbing that can be cured with trimming pinch-seam, possibly no trimming if you're sticking to the street only...watch those speed bumps
37" tires: don't try
The JK with stock wheels, 1 1/2" wheel spacer, 2" lift
33" tires: no rubbing
35" tires: some rubbing that can be cured with minor trimming of stock airdam, and fender flares/liners. Pinch seam trim recommended.
37" tires: don't try
The JK with stock wheels, 1 1/2" wheel spacer, 3" lift
33" tires - no rubbing, looks silly (lots of space between fenders and tires)
35" tires - no rubbing, trimming of pinch seam recommended
37" tires - minor rubbing with stock flares. No rubbing with flat flares. Proper bumpstop length and pinch seam trim necessary.
The JK with stock wheels, 1 1/2" wheel spacer, 4" lift
33" tires: no rubbing - entirely too much lift for the tire size
35" tires: no rubbing
37" tires: some rubbing (minor), none with flat flares - proper bumpstop length and pinch seam trim neccessary
38" tires: be careful - flat flares necessary, trimming necessary
39" tires: don't try without 1" body lift, trimming, and flat flares
The 1.5" wheel spacer will work as an alternative to new wheels, but many will recommend the replacement of your stock wheel as a safer alternative. This is an ongoing debate; regardless of your opinion on the matter, when buying a NEW AFTERMARKET WHEEL for a 12.5" wide tire, 4.7" backspacing is the MAXIMUM acceptable amount of backspacing to avoid using wheel spacers. 4.5" is recommended, and 3.75-4" is necessary for 14.5" wide tires.
