Another thing to consider with aftermarket rims on a dually is that in order to rotate them the tires have to be dismounted. I have alcoas which were on the truck when I bought it and they are nice, but you can't rotate them like steels. I almost got a set of 3rd gen steel wheels w caps from a TDR member but had a blowout on the rear tire and tire company made me a deal on six general grabbers ATs so went that route.
