Just notice that the 2021+ Model S snow chain is now available at Tesla Shop: Model S Snow Chains
Seems that it is using Konig K-Summit XL 55 Snow chain, which is also available here: https://www.etrailer.com/Tire-Chains/Konig/th02230k55.html
Maybe the one that comes from Tesla shop may already have the snow chain to properly set-up for the 19" wheel (according to Konig, you may need to remove 1 spacer to fit 19" wheel)
