Immunity to flats is just the beginning for a tire that could change your driving life.

We havephones that can survive being immersed,watches you can drag over a cheese graterandscreens you can fold without breaking, but a common nail can strand your car on the side of the road. Tires need to lose their air, but not that way.

Michelin is one of several tiremakers that have been developing airless tires but they seemed as improbable asGM’s early vision of self-driving cars. Now, however, the two companies are putting a pin in the calendar to haveairless tires on the market by 2024.

The first thing you notice about the airless Michelin Uptis, orUniquePuncture-proofTireSystem tires is that you can see through them. Glass fiber reinforced plastic vanes support the tread rather than air pressure.

From there, the benefits tumble forth: Nails become minor annoyances andsidewall cuts that usually render a tire unrepairableare no longer possible. There would be no need to check tire inflation (you’ve probably ignored my admonitionsto do that anyway) and we’d say goodbye to spare tires, jacks and inflation kits that most drivers view as mysterious objects anyway.Blowouts that cause thousands of crashes a yearwould be impossible.

Uptis tires also have a green angle: The promise toscrap 200 million fewer tires worldwide each yearby eliminating sidewall cuts and accelerated wear due to improper inflation. This environmental benefit will accrue regardless of which companies crack the code for airless tires.

Aspects I’ll watch on the road to the airless tire include:

  • What will theseweigh? The increasinglyelectric car world is lardy enough already.
  • How do theydrive? Driving purists will rend their vestments as they did over automatic transmissions and electric power steering, but the rest of us are open to better ride quality.
  • Are theyquiet?Tire contact is the main cause of noisethat emanates from freeways and inspiresall those ugly sound walls.
  • Will these be fullycompatiblewith today’s wheels or best suited to new ones designed for Uptis ?
  • Can existing autosafety systemslike ABS and stability control work properly with Uptis tires?
  • How well will theyshed snow, especially if it packs into the vanes and becomes ice?
  • What will theycost?

Airless tires will be an overdue leap forward. Today’s pneumatic ones date back as far as combustion engine cars, and we know which way those are going.
