New Michelin tires airless

Michelin opens first plant dedicated to production of airless tires

Because it doesn t require

I could be wrong, and probably am, but are they using the term 'radial' in a different way to what has been previously understood ? (ie radial or cross-ply?) Whatever, it's very interesting


Excellent bit of technology. It could really reduce the numbers of tires that are thrown away each year because of a puncture. I can see it causing problems though when you want to travel at high speed after you have driven through a puddle of mud and one half of the wheel is still loaded up with goo. The vibrations will shake you off the driver's seat. Also, can stones become wedged between the "spokes"?


Current airless tire designs a step in the right direction but best solution would be to invent a new light elastic material that can be filled into existing tires to permanently replace the air.

There are high tech materials called "airgel" which I think someday they maybe used to replace air in car tires.

Agree with fb36. Open sidewall design invites tire balance issues which will become only too obvious at speeds greater than 30 Mph. Anything (mud, leaves, a stick or a mouse) caught between the spokes will tend to screw up the works. Suggest this design incorporate a sloping surface starting at the longitudinal center-point where the spokes meet the outer wheel. This would tend to shed debris as the wheel turns, even if that debris where hardened mud, sand or other material. Its either that or prepare for a lot of F1-style swerving; in this case to rid the tires of junk rather than warming them up.


I imagine the reason Michelin is aiming these tires at the agricultural and industrial arenas is that the vehicles in those worlds don't go very fast (precluding the need to worry about stuff getting stuck between the 'spokes" and dangerously throwing the tire out of balance at high speeds). Perhaps a future version to be used on cars and similarly faster machines will have some kind of flexible skin covering the "sidewall" area to prevent debris from entering that space altogether.


"business segments within the low-speed application category"

Perfect for rental construction equipment such as skid-steer loaders, etc.

Long way to go to high speed private cars. Might be adaptable to busses with the mods mentioned above. I live the angled interior slope.

They've had vibration and noise problems in high speed testing. That's easy to fix by splitting the spokes left and right then slightly varying the spoke spacing.

It's the same thing they do with the tread blocks to prevent harmonic vibrations at various speeds.

Gregg Eshelman

Being in a an agricultural environment, I have severe reservations on these tires. They look like they would fill with mud and debris quickly, removing any displacement effect and making a very difficult situation with the changes of temperature that are a fact of life for most of us. I don't like flats, but I don't like being stuck or frozen either. I think a semipermeable, aramid membrane on the open side surfaces would be a good idea. Let's face it. These aren't going to cheap anyways

Frank Moores

You could easily block off the sides and let the air move between divisions internally, problem solved!

Steve Rock

Anyone care to offer an opinion as to the relative rolling resistance of these compared with LRR conventional tyres?

Martin Winlow

Instead consider using a variable density solid rubber design that would not be susceptible to sidewall debris loading. I cannot imagine side/torsional loading of the Michelin design being capable of sustaining necessary contact patch surface interface. I am not an engineer, just a layman observer.

Harold Dill

give em a chance, I'm looking forward to it
