As you are buying a new truck, it would be cool if the dealer would just swap out the tires for you...don't know if they will do that.
Another thing to consider; steel wheels are rated higher than aluminum. See if you can get steelies from a 1 ton SRW.
Let the dealer know what you are planning for your truck, maybe they will work with you.
Most dealers are clue-less about actually using trucks...you may have to educate them.

Most steel wheels are not rated higher than true forged aluminum. At least that's what I was told by 3 wheel companies. Was told my 17"x 8 forged aluminum were stronger and rated higher than steel.
Not likely...look at material properties for forged aluminum vs. steel. Big difference. You would need a alum wheel ~ 2x the size (thickness) of steel to have = strength.(Ever see a commercial truck w/alum wheels?)
Another thing to keep in mind is failure mode. Aluminum will fail catastrophically, steel will deform (and can be safely repaired).
Having said that; you can certainly get (forged) aluminum wheel of the proper rating to carry a TC.
But the steel vs. alum is something to keep in mind when wheel shopping...
