Self-healing car tires

We have a small all-electric car (Chevy Bolt) that does not carry a spare tire. Instead it is outfitted with Michelin Selfseal Tires. I was a little dubious these would work, but recently I had a tire puncture from a large screw in the tread, and the system worked well. The self-healing goo inside the tire kept the air in despite the puncture. But the screw was too big to remain. So in my garage at home, I pulled the screw out with pliers, which initially let some air out. Overnight the tire half-deflated. Next day I pumped it up again, let it sit for a few hours and it was as good as new. No issues. While this won’t work for gashes or huge punctures, I’d certainly consider Selfsealing tires for my next car. — KK
