While the number of cars with runflat tires continues to slowly grow, and the promise of airless tires is on the horizon, it seems that long forgotten self-sealing tires are finally reaching practicality. According to a recent article in the Detroit Free Press, Michelin tires with their Selfseal technology will be available on the 2020 Ford Explorer. They are already fitted to the Chevrolet Bolt EV. Michelin's Selfseal technology uses a coating inside the tire that can almost instantly fill in a nail or bolt hole up to a quarter of an inch in diameter. It works so well that many drivers may not realize they ran over something until days or weeks later when either the tire slowly goes flat, or the car's TPMS light goes on. The concept is similar to what cans of DIY self sealing compounds like Fix-A-Flat manage to achieve. Other brands such as Continental are starting to market self-sealing tires as well. Damage to self-sealing tires is usually only slightly more complex to fix and depends solely on the competency and experience of the tire retailer or repair shop involved.
