The tires will likely rub without new properly backspaced wheels or spacers. I wouldn't wheel it but I believe those are 33's and should fit. I think I read a build thread where they put on 35s before their lift on a JKU. Like I said, on pavement, you'll probably be fine but off-road, you could rub the flares or even the body. If you put them on and they rub, you'll know for sure but I doubt you'll damage anything. Those tires aren't that big.
