First off I would like to say what a great site this is.  I just purchased a new rzr and what to put some rims and tires on it.  I looked as some itp 108's with 25" bighorns on them.  the guy told me I would need some wheel spacers for the rear wheels or they will rub.  Is this true?  if so how do the polaris 26" rims and tires not rub.  Will aftermarket tires and rims make the rzr over the 50" trail width requirement. Is the ground clearance gained with a 26" worth the loss in performance. Thanks for any info
