I just watched that, and thought it was useful. It will be a long while before I need new tires, but it would be useful if I was in the market now.
I used to live less than an hour from TireRack HQ in South Bend IN, and bought all our tires direct from them for over 20 years - they would install them while you wait at HQ (probably not widely known?). They're a great outfit with fantastic reviews and guides even if you don't buy from them! And they had more makes/models of tires in stock than anywhere else by far.
