“No Flat, No Tube, No Stress”
That’s the slogan of the Tannus tyre company:
http://www.tannus.com/index_notube.html
Their tyres “Nymph” are made of some kind of foam, available in various sizes and the 16 x 1,25 version fits the Strida LT wheels.
13 different colors can be choosed, a few examples below:
As a first testing specimen, we’ve mounted Tannus tyres on a neon green Strida LT, it’s called the “Mamba”.
The “Mamba” is now located at Vienna’s first folding bike store das faltrad - test riders are welcome!
The black aluminium beltwheel is a product of Five Big Enterprise, Taiwan. 
My impressions:
Mounting of Tannus tyres is relatively easy, but a certain amount of hand force will be needed.
The required tool and two sets of tyre pins are supplied with each tyre.
For deinstallation of the original tyres and mounting of the Tannus tyres I needed 22 minutes.
I had just a short test ride, maybe 2 or 3 kms, and I mean these new tyres are doing their job very well.
Of course, it’s harder to pedal than before, I’d say that’s the price for the “no flat” function.
Customers should decide by themselves if they are willing to pay this price, anyway I’d recommend to give it a try.
Here’s the link to an installation video:

Many thanks to Genuine_S, the “Mamba” would not exist without his kind help!
