A donut should never be used for giving rides on Uber or Lyft platform. The donut tires are not for freeways, ever.
My donut blew out because it was ten years old. It was 3 am, and my insurance-paid tow service wanted to take me to the nearest 24/7 tire shop. I had never heard of one.
Went there, and they had me back in business in 10 minutes. The total charge for a used tire, balancing, and installation was $30 .
