I have a request. If anyone has an X with 33's or bigger and has any suggestions or advice how to have good articulation. I know now the X's have pretty good articulation but what can I do when I put 33's on it to keep from getting stuc in the ruts. I was thinking of different shock placement but will the torsion bar and leafs let you flex? Any advice is greatly appreciated and I love the pics. Thanks!

Tires don't change wheel travel, unless they contact the body or frame.

Disconnect the front and rear sway bars off-road, and you'll get a lot more travel.

But what happens when you get aftermarket rims with different back spacing? How big can you go and what can you get away with for back spacing and still keep you center of gravity low. I'm just looking for advice to see what other people have done to get the most clearance yet try to keep the center of gravity down low. Thank you for your time.

You'll find that the topic of aftermarket wheels has been discussed ad nauseum if you take a few minutes to review old topics.

offroadx is right but I will help you out a little I had 31x10.5s on my X when it was stock. Now I have a 2 inch body lift and put 33s. I also have American racing wheels (767 i think) with a backspacking of 4.00. They are a little wider than stock but you shouldnt have a problem.
