Tesla's wheels especially the 21" are very expensive. And they are easy to steal. I did some research and found this amazing lock that fits atleast the 19" wheels .. I think it should fit a 21" wheel also, but not sure. I am going to get 5 of these, and lock every wheel down. Normal wheel locks can be easily broken into, but these cannot be, and 5 of them - and your wheels are probably absolutely safe. Anyway this is the lock. Amazon says it doesn't fit Tesla, but it does. Just wondering if anyone has tried any alternatives? Or any other thoughts on how to keep your wheels safe/not stolen etc. If anything, I would think theives setting your car on cinder blocks might even damage the battery. So this protection is a must IMO.
