Go to Tirerack.com (I did this before for my BMW and now also to get two front 21s replaced on my GT because of a bubble). You buy them there online, and they will ship them to ANY store. You then have to pay only for the installation at that local store (80-100 bucks for 4 tires). Shipping takes 2-3 days. The insurance is typically included in the purchase.
In case something is happening you go to your tirerack.com account and see your orders (see screenshot below). You file a claim through their portal and boom.
They will ship again the new tires to ANY tire dealer.
I had to provide some photos, and it took 1-2 days, but then it was processed. It was a very easy process, IMO.Of course you have to pay upfront to accelerate the process.
