I'm looking to order winter tires only for my P3D with the existing 20" wheels. On Tesla's website, they are $5k with wheels and tires. They are coming with Pirelli SotoZero II (Model 3 20" Sport Wheel and Winter Tire Package). The 19" set comes with Pirelli SotoZero 3 (Not for P3D - Model 3 19" Sport Wheel and Winter Tire Package). I was going to purchase tires only and mount on the existing wheels and rotate in the summer/winter. Price installed was $1,500 Question: Any know why the 19" are using the newer SotoZero 3 whereas 20" are coming with SotoZero II? Has anyone installed the SotoZero 3 and have feedback? I've heard a lot of negative reviews on this tire; however, I'm looking for a good winter tire for daily driving in cold northeast temperatures, not really to drive through a blizzard. I was originally looking for the Bridgestone Blizzak tires; however, they only come in 235/45/20. Townfairtire.com says they will fit the car; however, Tesla service said they can't recommend that and would recommend staying with the 235/35/20. Thanks!
