Interesting question. Don't know that I've ever seen tires for sale on Black Friday.
Amazon has good prices on tires and lots of places there offer free shipping.
That said, I bought a set of BFG Mud tires for one of the Jeeps a couple weeks ago from Discount Tire (vendor here on the site). They matched the best price I found online, shipped free, and had 6 months with 0% interest to pay them off if you use their in-house credit card.
Tires showed up at my house in two days. Very happy with Discount Tire.
