I've dealt with Tire Rack in the past, both as an authorized installer and as a customer. Good company, had my order to me pretty quick.
Now, to answer Denny's question about the "2" in the A/T2 and M/S2 tires; Those are the second generation of those tires. The original A/T, which I have had a set of those on a different truck, has been discontinued for a few years now, the M/S has very limited availability, and looks to getting dropped soon itself.
