I got the spare tire on its rim.
Only problem is the local tire shop wouldn't put it on. They were being chicken chits about it.
But the shop that quoted me $180, plus tax in the next town over put it on for me, for $6.
So total price for a new spare was just under $90.
The date code on the tire was 2016 and that's good enough for me to call it new.
The date code on the ruined spare was 2004.
Yeah I would expect a 14 year old spare tire to shred on contact with the road under the weight of a car.
(Assuming that the spare got put on the car in 2018 and I found it in 2019)
2011 white SL leaf with 2014 batt.
