I have the Full Old Man Em set up 1.5" with new T bars. I cranked the T bar to match and aligned the front end. Then installed the 2" body lift so I think I can fit any size I want but I am worried about my rims as well. They are aftermarket 4X4 rims but still 16". I was thinking taller not wider so could have stiffer sides, but I am still reading the billion posts on tire arguments. <img src="/forums/images/graemlins/rolleyes.gif" alt="" />

you have aftermarket 15" or 16"??? 15" are OEM.
Be aware that if you put in a Gen 2 axle many wheels will not have a large enough hole in the center to fit over the rear axle. I posted the size diffences awhile back but I don't think it got archived.
You'll need a min. 108 mm for gen 2. Gen 1 are 97 mm if I recall.
Alot of arguement here,,,but 10.5 width tires are by man. recommened / designed for 7.5" rims. They will go on 6" but I think it would add to a squirmy feeling on highway, esp. going thru curvy roads.
On your T bar crank, you should (I can't think of the term, senior moment) nose should be a little lower than rear.
Make sure you get an alignment soon, and don't put it off cause things feel ok. I screwed around and toe in wore 2 tires.

Sorry, aftermarket 15s came off a raider my brother had in his wreaking yard. I spotted your offset writeup and then found your website. That is why I pulled them off of the raider, I knew nothing about offset till I saw your writeup. Good info. <img src="/forums/images/graemlins/kewl.gif" alt="" />
