Ahh, well then the only things you need to be concerned about are that (a) you have the proper bolt pattern of 5x5 or 5-127, (b) that the overall tire height doesn't go much higher than 33" unless you have a lift, and (c) that the backspacing on your new wheels is 4.5" or less.
If the dealer isn't giving you a discount, make sure you take the original Sahara wheels/tires to sell on Craigslist/eBay afterward. If the dealer keeps them, he should credit you quite a bit toward the cost of the Jeep.
If you can't get all this sorted out in a way that isn't confusing, I'd just handle it aftermarket. Take the Jeep as-is for whatever price you've arrived at, and then go through Discount Tire or another wheel/tire company to get your wheels/tires taken care of.
