I am building an off-road trailer and am going to put rims and tires on it that match my Roxor.  I have aftermarket tires though... I found the wranglers not to be nearly aggressive enough.  I can buy the rims from Sherwood tractor for $41 each and the tires are $123 on CARID.  
I know there are several people on here maybe looking to change from alum to steel or wanting to add a spare.   You might be able to separate the tires and rims and sell them quicker that way.  Just a thought.
