OK, for those interested in my snow tire thinking (no one? Bueller?), the current plan to beat is: I will have the 20 AT 3 peak tires and try those out with snow mode on ice/snow. If it is no good or I get any side skidding on roads, I am going to buy 4 Blizzak LT winter tires (unstudded ones) and have a shop mountain for like 25 per tire 2x per a year.
I considered other options like just buying 4 more Rivian rims (pretty expensive) and 4 Blizzak tires; or cheap rims that will fit Rivian and 4 Blizzaks and just mounting them myself, but if we are talking an hour a year and 200 a year, that is better than 2-3000 up front for Riv rims, and other mfg Rims may make the computer range calculator go crazy (though others have done this and not had a problem).

Note this person did this before Snow mode came out.
Well with some snow in the forecast we decided to swap over to some 20” Blizzak LT snow tires. These are in the stock size, I think they are a few pounds heavier than the stock pirellis. Rivian would not install aftermarket tires so I had discount tire do it, I removed the panels to try to save...
