I've, unluckily, had 2 tire failures. First was piece of someone else's rim going though center of rear 21" staggered tire causing blow out at 40+ mph at ~1 month old, second was nail though front right 21" at 7 months.
Each time the tire had to be replaced. Zero chance the first could be patched, second could have been though SC said not able to. So definitely a lot more than $50 ;-)
I have to say Tesla roadside assistance was exemplary. Both times they had me ensure the car was somewhere safe and got me an Uber home each of the evenings. Car was ready next day and SC kept me informed. Couldn't have asked for better.
