Will this tire fit on a stock X?

Pro Comp Xtreme M/T Tire LT285x70R-17
overall height is 33"

 

It might be tight. I am putting on Procomp All Terrains 33x12.50x17 and using a 2" Budget Boost lift so that I know I will have the clearence. The size tire you are asking about is close to what I am getting. I hope this helped you out.

 

That should fit, but that is about the largest I think you could go on a "Stock X" before you start to have issues.

 

From what I've seen on JK's up here the width of the tire is more of a limiting factor then the height. The front tire almost hits the sway bar with the stock 32.5" tires.
1.5" width wheel spacers will get out off the sway bars but then you may want extended bump stops to keep them from hitting the underside of the fenders.
This is stock height with 265/75/17's (32.5")

 

They will fit, but you may encounter rubbing at full lock or articulation. Many run wheel spacers to remedy this.

 

Stock tire size is 255/75/17, or 32.06".

 

I hate to state the obvious, but if you're running 16" wheels, then those 17" tires are gonna be a problem. (You said, "stock x" and your sig shows 16" wheels)
