At my test drive this weekend in Toronto I was told that Tesla will soon officially announce their winter wheels/tires packages for Model S. Prelim info is they will offer 2 options, both on the 19" rims currently being offered with all-season tires (I'm assuming 245/45/19): - Option 1: non-studded Pirelli winter tires (no info yet on which ones), set of 4 for $2400 - Option 2: studded Nokian winter tires (no info on which one but I'm assuming Hakkapeliitta 7), set of 4 for $2800 No word yet on the availability/pricing of purchasing just the extra set of 19" rims. For general reference, price on TireRack.com for Pirelli Winter Sottozero Serie II (Performance Winter/Snow) are $271 each ($1084 for a set of 4); price on Tiresbyweb.com for Nokian Hakkapeliitta 7 (studded) are $339 each ($1356 for a set of 4). I've never had to switch between summer and winter tires (I've used all-seasons on my previous and current rides), but since I'm going with the 21" performance tires, being in NE Ohio, I'll need to switch to either all-season or winter tires from November to March. So pending availability/pricing on the extra set of rims, I'll most likely be purchasing from Tesla Option 1 mentioned above. Thoughts on pricing, choice of tires by TM?
