I just sold my Chevy truck and the guy didn't want to pay the extra for the Mickey Thompson Challenger wheels and the BFG T/A Kos, so I kept them. The rims are 15x8 with a 4" backspacing, am I going to need to run some one inch spacers to get these to work on the FJ40 I'm looking at, or would I be better off selling these and looking for others. It took me forever to find a set of these wheels since they've been discontinued for a while now.
