I went from 215's to 235's on stock rims and stock suspension. My suspension measures witin 1/2" of factory specs which right off I can't remember. Anyway I have no rubbing issues at all. Can't see you having a problem with 225's and those rims UNLESS your suspension is really weak. And maybe not even then.

 

Thanks for every ones help i put 235/75/15's on those after market rims and it's good now. No rubbing and the wobble is gone. Here's the pictures, also by the way there is a button in the glove box. What is that for?

 

Death wobble, why I keep my XJ Stock!!!!
