I recently tried to order a set of Michelin tires through TireRack (November 2021) The order was placed into backlog more the 5 times with each new deadline coming then getting pushed out by weeks, literally 1 day before the tires were set to arrive. The last order was being pushed from January 17th to February 18th 2022 (3 months for my initial purchase).
Ultimately I cancelled my order as I felt scammed by TireRack.
We understand your frustration. The tire industry, like most industries, has experienced unforeseen closures and shipping delays. Please know we are doing our best to get backordered products restocked as soon as possible.
