Yup. You call Tesla for a tow, or you can call AAA for a tow, or you stock up on some basic tools to fix it yourself (jack, sockets, plug kit, and pump).
I've been meaning to put together a "kit" for road trips myself. This thread got me to pull the trigger. I have a breaker bar and sockets and I just ordered these items...
Amazon.com: Stop & Go 1085 Deluxe Tire Repair Kit: Automotive
Amazon.com: Torin T10152 Scissor Jack - 1.5 Ton: Automotive
I also have the Tesla branded "slime" emergency repair kit that I would use the pump from to reinstall (
Tesla — Tire Repair Kit). Or, and more likely, I usually always have a bicycle floor pump in the car on trips as I usually have a bicycle with me.
Cheers!
