Well I hope they do.
I'm just going by what I read in the post By 4lift
Largest tire on stock JK? Here's your answer!
On Aftermarket Wheels
"As I mentioned initially, the stock wheels have a backspacing of 6.25”. This is too deep of a backspace to allow proper clearance for a decently wide tire. The general consensus is that the “magic number” for backspacing for the JK is 4.5” or less. It does not mean you can't run a wheel with 4.6”+. But 4.5” and under is the safest bet.
Many 15” wheels have less (sometimes a lot less) than 4.5”. That's so the wheel clears the brake calipers. Most 15” wheels come with 3.75” of backspacing (MB72, MB TKO, etc). There are a few that come with more (such as the Black Rock 909 – 4”) and some that come with less (such as the Level 8 Tracker – 3.32”). Just remember, the lower the backspace number, the further out the wheel will sit from the Jeep body. One of the most common wheel/tire combos on this site is the 15x8 MB 72 wheel with 33x12.5x15 Duratrac tires. Dozens of people run this setup without a single issue on the street. However, just like most of the other 33” combinations, you can get some fender contact when offroad.
Also, be aware that, while many 15" alloy wheels will fit over the Wrangler's brake calipers, most 15" steel wheels will not. "
