As above, just put a little differently, three possibilities will cause the tires to protrude out further than normal. Wheel spacers, wheels with insufficient backspacing, and/or running extra-wide wheels like 15x10.
Wheel spacers are obvious, you either have them or you don't. Some people install wheel spacers just to make the tires stick out further. Others install spacers that are actually bolt pattern adapters... they adapt a wheel whose bolt pattern wouldn't normally fit a Wrangler so it can be bolted on. Adapters and spacers do the same thing, they move the wheel further outwards at least an inch or so.
The last one is wheel backspacing. Factory wheels have 5.25" to 5.5" of backspacing. Backspacing is the distance between the inner-most edge of the wheel and the wheel's mounting surface. The yellow tape measure is directly measuring the backspacing in the below photo.
If you go from a 15x8 wheel with 5.25" to another 15x8 with 3.75" of backspacing, for example, that will move the wheel and tire outward 1.5". If you instead went to a 15x10 wheel with the same 3.75" of backspacing, the wheel itself would still be 1.5" further out but its outer-most edge and the tire's outer sidewall would be two inches further out due to the wheel's 2" wider width.
So you can see that any or a combination of the above three adapter/wheel spacer-adapter/wheel width issues above can cause your wheels to protrude out further. See if you have wheel adapters installed, figure out if you have 15x8 or 15x10 wheels, and then measure the backspacing like is shown above. Report back and we can give you advice on how best to get them positioned more appropriately.
