Umm, you do realize you can get a flat tire on a Tesla fixed anywhere? Most places will fix them free. Pump the tire up, go to a tire dealer, get it fixed. Yes, Teslas should come with a tire pump. They don't. Buy one for $30. Buy a jack if you want one. Another $30. 21 mm lug nuts are really, really common. It's not rocket science. If you want to be self sufficient learn a little something about cars, buy a few basic tools. The jacks and lug wrenches that come with 99% of cars are junk anyways. If you really plan on using either, buy a decent set regardless of your car. If you don't, call a mobile tire repair. Kids these days.
