I had to come back to say, discount tire direct is probably the best place to go in the end. After searching all the sites I mentioned earlier (at least 17), I found the best price on the tires I wanted, called discount tire direct, and without hesitation, they beat the price. They also weren't advertising the rims I wanted, so I asked about them, and even with special ordering them, the rims were the cheapest price as well. With a few add-ons, the rims alone were about $100/total cheaper than the next closest. Free shipping, mounting, and balancing.
Another thing to add, tire prices change weekly, if not daily. It was about 5 days between the time I made the spreadsheet and when I went to order. 95% of the tire prices had changed, and unfortunately for me, the price of the tire I wanted had increased significantly. Cheapest price went from $1216 to $1500.
Long story short, I would figure out what tire you want first. Wait until you are absolutely ready to buy. Search a bunch of sites to find the best deal (make sure to include shipping cost), then call discount tire direct or fill out a price match form, and buy from them.
