I decided to order Nokian Hakkapeliitta R2 winter tires (I assume I'd just use the retailer locator on their site), and will get an extra set of wheels so there is less risk of tire damage while mounting/unmounting. What size do you recommend if not the standard 245/45R19? I heard smaller may be better. Also for the wheels should I order through Tesla to ensure the TPMS works and then have them mount the Nokians on it or can you tell me where to get good wheels at a decent price outside of Tesla? Thanks all, sorry if this is covered in the Winter Tire recommendation thread just didnt have time to read it all.
