Man I'm running the 4WP Xtreme black steel wheels on mine and it does fine. They're 15X8's with BFG 33X12.50 Mud Terrains on them.
Balanced just fine the day I bought them, been doing fine ever since.
I like the look of the wheels...don't know if plain old black wheels make it look cheap, but I'm more of a function over form kind of person. To each his own I suppose...heck I didn't even put the center caps on.
For only $42 a piece, you can't beat them. Plus, last thing I would want to do is take my pretty bling blinging rims offroad and tear the crap out of them.
Good luck with your decision! You're not having second thoughts about selling that guard are you?
I was looking forward to taking that off your hands!!
