Looking into this question too, as winter in Minnesota is probably too much for the 19" all seasons. Customer service recommended the Pirelli Sotozero 3 245/45R19 102V XL and quoted a set of 4 at $1,485 plus tax, but said their mobile tire van is not set up yet, so I would have to come in to the service center. Can't do that as they're 400 miles away.
Called Tire Rack, and asked about availability, and they said that the above Pirelli is only available thru Lucid, but recommended the Vredestein's Performance Winter / Snow tire and quoted $1,052 plus tax, with a $130 mobile installation / mounting & balancing included.
The Vredestein's get good reviews, though are not rated for EV's as they don't have the low rolling resistance, which will effect the range. Still, I'm inclined to go with them, but the issue I'm not sure about is whether there is any additional calibrating that needs to be done when different (than OEM) tires are put on...anyone know if that's a real thing?
The mobile installation by Tire Rack (or if available via Lucid) is a nice way to deal with swapping out the tires, and I'd happily make room in the garage for them.
