Criminals would love this as a way of foiling police stinger devices.

This product pops up every few years to great fanfare and then we never see it again until the next time it pops up.So I'm not holding my breath waiting for this to be common place.

They are for sale in USA MICHELIN® Tweel® Family of Products (michelinman.com) not sure about cars though not looked

I believe foam-filled tyres are available for bicycles, and I would be interested in those since the fashionable rim and tyre designs are getting stupider and more fragile here in Taiwan.

Just buy a bigger and/or more puncture resistant tyre. The only restriction to the size is that there is enough frame and fork clearance for your choice of tyre.

Somewhere (presumably internyet, but I don't remember. If anyone has the source let me know) I've seen a description of a bike tyre substitute in use in Germany in the immediate post war, The Third Man stylee period.

This involved a lot of rubber disks (either derived from old bike or old car tyres, Can't remember which) strung on a circumferential wire, making up a semi-solid tyre. Nothing new under the sun.

That'd be a lot of work if you didn't HAVE to do it, but it would be interesting to see how bad it was.

Maybe something involving bits of rubber hose could be implemented quicker.

Old mountain biking hack. By the nature of the terrain, punctures and cut tyres are not unusual. Most carry a basic repair kit with them but some more severe damage, like a slashed sidewall, are not easily fixable on the trails. Often you can be several miles from civilisation too. One trick is to pack the damaged tyre with grass or leaves. It can be enough to make the bike rideable for a short while at low speeds.

Coastal touring you could use Bladder-Wrack, a natural pneumatic filling.

Bit salty though

Couple of points, re my earlier comment.

You could buy a more suitable (for your needs) rim as well as a stronger tyre.

As for the tubes, surely you can buy the correct size online if bike shops don't stock them?

You do get tubeless tyres for bikes, presumably these could be 'fixed' by the squirty foam in the same manner as car tyres?.

Finally, I thought the fad bicycles (re tyres) these days was the 'fat' tyres?. Most suitable for snow or sand, which is presumably what they were designed for, but probably good on heavily potholed road surfaces. Of course you can't fit them to any frame/fork not designed to accommodate them!.
