The wheel size and lug pattern are not the problem. Those will work on your YJ. The problem you will have is the backspacing on the wheel.
Specially running a 33X12.50, too much back spacing (like a stock wheel) and the tire is going to rub the front springs when you turn.
And your wheel wells are going to be stuffed completely full of tire with only a 2.5" lift and trying to run 33" tires. I hope you plan on keeping it a mall crawler, cause it isn't going to like chewing on those Duratracs when its off road.
