The ultimate "run flat" tyre?

Of course, if it's been around for a couple years - the question begging to be asked is "Why is it not commercially available?"

The obvious answer is "Because it was not designed and commercialised by the big tyre companies." Vested interest, anyone?

I Think you will find it was a Michelin development from at least 20 years ago.

You wouldn't be able to let the tyres down to get out of trouble if needed....or pump them up for a heavier load.

As others have said this tyre technolgy is not new and there are a number of other tyre technologies in use in various areas.

many competitive off road motorcycles use a "mousse" rather than a tube..its a sort of foam thing.

There are other semi-solid and filled tyre technologies used in foresrty, mining and military use.

BUT they all have issues that make then unsuitable for general use.

If you wantch the video, you will see that the vehicle rocks back and forth when stopping and starting, because the tyre design is rotationally sloppy.
This would make the tyre very .."interesting"... under brakes and it would tend to chatter where traction is variable.

Also note the tyre is pretty well flat treaded, this will mean that it will only work well on fairly flat surfaces.

In propper off road situations those cells would fill up with rocks and sand and mud.

Yes and as mentioned it is a fixed pressure tyre so it would have to me matched to a specific load and coule not have the pressure reduced to improve flotation.

In its application it would be a great thing...but its application is very narrow....probably limited to urban warfare and riot vehicles...and at fairly low speeds

Most unlilkly to be ever approved for general highway use.

OH and it would be expensive.

Like many things....I don't see the old pneumatic tyre being replaced any time soon.

Hi Bantan
You made some great points, I was talking it over with hubby (Mick) and we brought over the same points as you, he thought they would be more designed for over in the sandy desserts of Iraq, spoke to Micks brother SAS soldier and he said Australians didn't use them. More American technology definitely has draw backs with rocks, tyre pressure no way of changing it etc. But who knows one day something might be invented to suit all terrains. For know I will stick with my desert duellers on my 75 series cruiser.
Cheers mate

Oh and the tyre structure would probaly wear out before the tread did..and on the way it would get pretty sloppy.

Motorcycle mousses tend to require changing, changing due to becomming soft and baggy, many times before the tyre wears out.

Try these.


Pommy design seen in Scotland recently and apparently road legal there.
Simply "bolt on".
There is also a US version.

Yes, the US version is Sno-Cat. It is/was used in the Antarctic by the Aussie contingent there.

Sno-Cat

I saw some on a new quad at the bike shop the other, probably great for that type of thing.
