I'm gonna go ahead and disagree with the lot of you.
You should go with some AR Teflon coated Mohaves, throw some meaty BFG Mud Terrains on there and you will be looking tough as nails.
Man, when I saw Scott H's IronMan in Moab, all I can say is wow, IronMans with black rims and big meat look so d@mn good.
Forget the bling.
