I have a 2005 3500 4x4 dully and want to put some more aggressive tires on it. My wheel size is 16 and I currently have Normal street tires on it. Does any one have any suggestion for me. If I have to put spacers on it i am ok with that. I don't have the funds to lift it or a leveling kit right now. Any feed back would be greatly appreciated. Oh and I work offshore for half the yr and does not get driven every day when I'm home so if that makes any difference.
