Spare tire and wheel for Model S. Nice to have on long trips. I have this wheel and tire that fits any Model S. It is 19" but will serve as a spare even if you have 21's. I carried it with me for long road trips. It will even fit in the frunk if you have the earlier large frunk $100. I am in Ventura, CA. I am not going to ship this, I am hoping to find a local buyer.
