Having just bought a Bolt
Having just bought a Bolt with these tires and no spare, I have been trying to figure out my best solution to dealing with tires. I've decided to keep the self-sealing tires and add a full size spare with the same tire. Since the existing tires still have a reasonable amount of tread, I'll run them until they need to be replaced, but I am not comfortable without a spare, and it really needs to be the same tire that is on the car if a flat occurs on the front because of the way the electric motor is connected to the wheels. So I will buy one Michelin self-sealing, put it on a Cuze wheel of the same size, and carry it as a spare, and replace with the same tire so if my wife picks up a nail, she may not have to change a tire. Best of both worlds. The performance of the tires is good enough for me, and peace of mind is more important.
